Add incremental RST-to-MyST swap mechanism (#1857)

* feat: add swap_sources.py for incremental RST-to-MyST migration

Pre-build swap/restore script that renames md-{name}.md → {name}.md
before Sphinx builds and restores after. Includes state tracking,
exclude file generation, collision detection, and partial-failure
rollback. 10 tests cover all specified behaviors plus rollback path.

* feat: add import_myst.py for importing MyST files from myst/* branches

Adds scripts/import_myst.py with import_page, git_show, list_myst_files,
list_rst_files, and do_import. Imported files are written as md-{name}.md
alongside existing RST files; importing is decoupled from swap activation.

Adds tests/test_import_myst.py covering single-page write, identical-skip,
warn-on-different-without-force, force-overwrite, and nested-path creation.
All 5 tests pass on Python 3.9.

The atexit handler in --swap mode caused immediate restore on process
exit, breaking standalone usage. Makefile trap and RTD post_build
handle restore reliably.

* feat: activate quick-start as MyST canary via swap mechanism

Imports docs/md-quick-start.md from origin/myst/current and adds
quick-start to docs/_swap.txt. Validates the swap pipeline end-to-end
on one page: import_myst pulls the MD via git show, swap_sources
renames md-quick-start.md to quick-start.md, sphinx-build renders
quick-start.html with zero MD-specific warnings, and restore reverses
the rename cleanly.

* feat: activate 106 visual-validated canaries via swap

Imports 105 MD files (plus quick-start already present) from
origin/myst/current and adds them to docs/_swap.txt. The selection
is the BackstopJS visual-passers cohort: pages with <5% rendered
diff vs the live RST docs at docs.vyos.io/en/latest/, filtered to
those with an RST counterpart on current and no cmdincludemd usage
(template-format reconciliation pending).

Local sphinx-build with all 106 swapped: succeeded with 100
warnings (vs 95 baseline). The 5 new warnings are all undefined
cross-reference labels, not build failures:
- contributing/development.md (missing 'coding-guidelines')
- operation/upgrade-recovery.md (3 missing 'how_it_works' /
  'cancelling_recovery')
- vpp/configuration/dataplane/{buffers,memory,unix}.md (missing
  'vpp_config_dataplane_*' labels)

* fix: re-import 4 canary md-*.md files with xref label fixes

Re-imports the dash-form-corrected versions of:
- contributing/md-development.md (added (coding-guidelines)= anchor)
- operation/md-upgrade-recovery.md (3 ref renames: how_it_works /
  cancelling_recovery -> dash form)

Source: origin/myst/current commit 59fbe3ea. Verified locally: clean
swap-build no longer reports any of the 5 target labels (1 of 6 —
vpp-config-hugepages — remains because system.md isn't in the canary
swap list; that anchor lives there).

* fix: re-add 4 canary md-*.md files deleted by 242b334a

Commit 242b334a accidentally staged deletions instead of modifications
because the working tree had unprefixed *.md files left over from an
incomplete swap-restore cycle. Re-imports the same 4 files from
origin/myst/current with the xref label fixes applied:

- contributing/md-development.md       — (coding-guidelines)= anchor
- operation/md-upgrade-recovery.md     — how_it_works → how-it-works,
                                         cancelling_recovery → cancelling-recovery

* fix: resolve remaining xref label gaps in swap-active build

Three small additions clear the cross-reference warnings tied to
underscore-vs-dash label form mismatches and the vpp-config-hugepages
reference that previously needed system.md in the canary set.

- system.rst: add .. _vpp-config-hugepages: alongside the existing
  underscore label so memory.md references resolve regardless of
  whether system.md is swap-active.
- md-lcp.md: add (vpp_config_dataplane_lcp_ignore-kernel-routes)=
  alongside dash form (carries upstream from myst/current 079fa786).
- md-memory.md: add (vpp_config_dataplane_memory)= alongside dash
  form (also from myst/current 079fa786).

Local clean swap-build with 106 canaries:
  before: 305 warnings, 8 undefined-label entries in our scope
  after:  300 warnings, 0 undefined-label entries in our scope

Remaining undefined-label warnings (release-notes, prepare_commit)
are in documentation.rst and unrelated to the canary swap mechanism.

* fix: re-add md-lcp.md and md-memory.md (deleted by 870c9e7e)

Same disaster pattern as 242b334a: a swap-restore cycle left
unprefixed *.md files in the working tree, and the subsequent
git add staged deletions instead of modifications. Restoring the
two affected md-*.md files from origin/myst/current 079fa786
(which has the dual underscore+dash anchors needed for the
swap-active build).

* fix(swap): address Copilot review feedback on swap infrastructure

Category D — drop obsolete canary mechanism settings:
- conf.py: remove '**/md-*.md' from exclude_patterns (no canaries left)
- Makefile: replace malformed '*/_build/*' with '$(BUILDDIR)/**' and drop
  the '*/md-*' ignore (canary files no longer exist)

Category C — script robustness:
- import_myst.py:
  * list_myst_files() now raises SystemExit on git ls-tree failure instead
    of silently returning [] (would have masked typo'd --source refs)
  * list_rst_files() skips _build/ when scanning for .rst stems
  * import_page() rejects stems containing '..' or absolute paths and
    re-checks that the resolved destination stays under docs_dir
  * --dry-run uses a separate "would_import" counter; summary line now
    distinguishes dry-run from actual imports
- swap_sources.py:
  * parse_swap_list() reads with explicit encoding='utf-8'
  * do_restore() validates state file version + entry shape before
    renaming files; raises with actionable message on corruption
  * State file reads/writes use explicit encoding='utf-8' throughout

_swap.txt:
- Wrap long comment line to satisfy 80-character doc-linter limit

* refactor(swap): rename imported .md files to md- prefix for swap mechanism

Restore the canary file naming convention that swap_sources.py expects:
the imported MyST pages now live as docs/<dir>/md-<name>.md alongside
the existing docs/<dir>/<name>.rst, so swap_sources.py --swap can rename
them into place at build time.

- 254 .md files renamed (every page with a matching .rst counterpart)
- 2 MyST-only pages left at their final names (no .rst exists, no swap
  needed): docs/copyright.md, docs/automation/terraform/terraformvyos.md

All 114 stems listed in docs/_swap.txt now have a corresponding
md-<name>.md source file ready to swap in.

* docs: address CodeRabbit review feedback on imported MyST pages

Fix issues flagged by CodeRabbit on PR #1857. All issues are pre-existing
in the upstream RST docs and inherited by the MyST conversion.

Real bugs:
- inter-vrf-routing-vrf-lite.md: invalid IPv6 next-hop "2001:db8::*" →
  "2001:db8::1"
- ipsec-pa-route-based.md: vendor mislabel "Cisco" → "Palo Alto"
  (header on line 39 and "Monitoring on Cisco side" section heading)
- bgp-ipv6-unnumbered.md: AS number mismatch between configuration and
  verification output for both routers (Router A: 65020 → 64496;
  Router B: 65021 → 64499)
- qos.md: class 30 used "match ADDRESS20" instead of ADDRESS30 — broke
  the documented pattern (classes 10/20/30 → ADDRESS10/20/30)

Security:
- OpenVPN_with_LDAP.md: redact full PEM private key material from the
  three "set pki ... private key '...'" lines and from the embedded
  OpenVPN client <key> block; replace with <REDACTED> / ...REDACTED...
  placeholders. Public certificates retained.

* feat(swap): default to serving MyST for all swapped pages

Replace the previously-curated 114-stem _swap.txt with the full set of
254 imported md-prefixed pages, so MD is served by default at build
time. To revert any specific page back to RST, remove its stem from
_swap.txt (or comment it out).

* fix(ext): handle RST fallback in CmdInclude when _renderer absent

`cmdincludemd` is in `myst_fence_as_directive`, so MyST routes
fence blocks through `render_fence → render_restructuredtext →
MockRSTParser`. In that path `self.state` is a plain docutils Body
with no `_renderer`, crashing the build.

Fall back to `nested_parse` when `_renderer` is unavailable so the
directive works in both MyST and RST/MockRSTParser contexts.

* feat(conf): copy .md sources into HTML output for plain-text serving

Adds a build-finished hook that mirrors every .md file from the Sphinx
source tree into the HTML output directory verbatim, making unrendered

+# Wireless LAN / Wi-Fi
+
+{abbr}`WLAN (Wireless LAN)` interfaces provide 802.11 (a/b/g/n/ac) wireless
+connectivity, referred to as Wi-Fi, and operate in one of the following
+modes:
+
+- {abbr}`WAP (Wireless Access-Point)` mode provides network access to connecting
+  stations if the physical hardware supports acting as a WAP
+- Station mode acts as a Wi-Fi client accessing the network through an available
+  WAP
+- Monitor mode lets the system passively monitor wireless traffic
+
+If the system detects an unconfigured wireless device, it will be automatically
+added to the configuration tree, specifying any detected settings (for example,
+its MAC address) and configured to run in monitor mode.
+

+### Wireless options (Station/Client)
+
+The example creates a wireless station (commonly referred to as Wi-Fi client)
+that accesses the network through the WAP defined in the above example. The
+default physical device (`phy0`) is used.
+
+```none
+set system wireless country-code de
+set interfaces wireless wlan0 type station
+set interfaces wireless wlan0 address dhcp
+set interfaces wireless wlan0 ssid 'TEST'
+set interfaces wireless wlan0 security wpa passphrase '12345678'
+```
+
+Resulting configuration:
+
+```none
+system {
+  wireless {
+    country-code de
+  }
+}
+interfaces {
+  wireless wlan0 {
+    address dhcp
+    security {

+        passphrase "12345678"
+      }
+    }
+    ssid TEST
+    type station
+  }
+```
+
+### Security
+
+{abbr}`WPA (Wi-Fi Protected Access)`, WPA2 Enterprise and WPA3 Enterprise in
+combination with 802.1X based authentication can be used to authenticate
+users or computers in a domain.
+
+The wireless client (supplicant) authenticates against the RADIUS server
+(authentication server) using an {abbr}`EAP (Extensible Authentication
+Protocol)` method configured on the RADIUS server. The WAP (also referred
+to as authenticator) role is to send all authentication messages between the
+supplicant and the configured authentication server, thus the RADIUS server
+is responsible for authenticating the users.
+
+The WAP in this example has the following characteristics:
+- IP address `192.168.2.1/24`
+- Network ID (SSID) `Enterprise-TEST`
+- WPA passphrase `12345678`
+- Use 802.11n protocol
+- Wireless channel `1`
+- RADIUS server at `192.168.3.10` with shared-secret `VyOSPassword`

+## Examples
+
+The following example creates a WAP. When configuring multiple WAP interfaces,
+you must specify unique IP addresses, channels, Network IDs commonly referred
+to as {abbr}`SSID (Service Set Identifier)`, and MAC addresses.
+
+The WAP in this example has the following characteristics:
+- IP address `192.168.2.1/24`
+- Network ID (SSID) `TEST`
+- WPA passphrase `12345678`
+- Use 802.11n protocol
+- Wireless channel `1`
+
+```none
+set system wireless country-code de
+set interfaces wireless wlan0 address '192.168.2.1/24'
+set interfaces wireless wlan0 type access-point
+set interfaces wireless wlan0 channel 1
+set interfaces wireless wlan0 mode n
+set interfaces wireless wlan0 ssid 'TEST'
+set interfaces wireless wlan0 security wpa mode wpa2
+set interfaces wireless wlan0 security wpa cipher CCMP
+set interfaces wireless wlan0 security wpa passphrase '12345678'
+```
+
+Resulting configuration:
+
+```none
+system {
+  wireless {
+    country-code de
+  }
+}
+interfaces {
+  [...]
+  wireless wlan0 {
+        address 192.168.2.1/24
+        channel 1
+        mode n
+        security {
+            wpa {

+                passphrase "12345678"
+            }
+        }
+        ssid "TEST"
+        type access-point
+    }
+}
+```
+
+To enable access point functionality, configure a DHCP server for this
+interface's network, or add the interface to an existing local bridge
+(see {ref}`bridge-interface` for details).
+
+### Wi-Fi 6/6E (802.11ax)
+
+The following examples configure Wi-Fi 6 (2.4 GHz) and Wi-Fi 6E (6 GHz)
+{abbr}`APs (Access Points)` with the following parameters:
+- Network ID (SSID): `test.ax`
+- WPA passphrase: `super-dooper-secure-passphrase`
+- Protocol: 802.11ax
+- Wireless channel for 2.4 GHz: `11`
+- Wireless channel for 6 GHz: `5`
+
+#### Example configuration: Wi-Fi 6 at 2.4 GHz
+
+You may expect real throughput around 10 MB/s or higher in crowded areas.
