feat: flip swap mechanism — MD as primary, RST as override (Phase 1)

This is the first of three phases inverting the per-page swap mechanism
so MD becomes the canonical primary and RST becomes the rare override.

Phase 1 — file renames + conf.py exclude_patterns flip only:
- Rename docs/**/md-<stem>.md to docs/**/<stem>.md (drop md- prefix)
  for all 254 stems previously listed in docs/_swap.txt
- Rename docs/**/<stem>.rst to docs/**/rst-<stem>.rst (add rst- prefix)
  for the same 254 stems
- Repurpose docs/_swap.txt as docs/_rst_overrides.txt; initially empty
  comment-only since no pages need the RST fallback right now
- conf.py exclude_patterns flipped: rst-*.rst is now excluded by default
  instead of md-*.md
- conf.py runtime-artifact references updated to _rst_override_state.json
  and _md_exclude.txt (Phase 2 will rewrite swap_sources.py to produce
  these names; for now no swap script runs because overrides list is empty)

Phase 2 (next commit on this branch) will rewrite scripts/swap_sources.py
with inverted rename direction, delete scripts/import_myst.py + tests, and
update tests/test_swap_sources.py for the new semantics.

Phase 3 will be the cleanup pass and ready-for-review flip.

-# IGMP Proxy
-
-{abbr}`IGMP (Internet Group Management Protocol)` proxy sends IGMP host messages
-on behalf of a connected client. The configuration must define one, and only one
-upstream interface, and one or more downstream interfaces.
-
-## Configuration
-
-```{cfgcmd} set protocols igmp-proxy interface \<interface\> role \<upstream | downstream\>
-
-* **upstream:** The upstream network interface is the outgoing interface
-which is responsible for communicating to available multicast data sources.
-There can only be one upstream interface.
-
-* **downstream:** Downstream network interfaces are the distribution
-interfaces to the destination networks, where multicast clients can join
-groups and receive multicast data. One or more downstream interfaces must
-be configured.
-```
-
-```{cfgcmd} set protocols igmp-proxy interface \<interface\> alt-subnet \<network\>
-
-Defines alternate sources for multicasting and IGMP data. The network address
-must be on the following format 'a.b.c.d/n'. By default, the router will
-accept data from sources on the same network as configured on an interface.
-If the multicast source lies on a remote network, one must define from where
-traffic should be accepted.
-
-This is especially useful for the upstream interface, since the source for
-multicast traffic is often from a remote location.
-
-This option can be supplied multiple times.
-```
-
-```{cfgcmd} set protocols igmp-proxy disable-quickleave
-
-Disables quickleave mode. In this mode the daemon will not send a Leave IGMP
-message upstream as soon as it receives a Leave message for any downstream
-interface. The daemon will not ask for Membership reports on the downstream
-interfaces, and if a report is received the group is not joined again the
-upstream.
-
-If it's vital that the daemon should act exactly like a real multicast client
-on the upstream interface, this function should be enabled.
-
-Enabling this function increases the risk of bandwidth saturation.
-```
-
-```{cfgcmd} set protocols igmp-proxy disable
-
-Disable this service.
-```

-
-### Example
-
-Interface eth1 LAN is behind NAT. In order to subscribe 10.0.0.0/23 subnet
-multicast which is in eth0 WAN we need to configure igmp-proxy.
-
-```none
-set protocols igmp-proxy interface eth0 role upstream
-set protocols igmp-proxy interface eth0 alt-subnet 10.0.0.0/23
-set protocols igmp-proxy interface eth1 role downstream
-```
-
-
-## Operation
-
-```{opcmd} restart igmp-proxy
-
-Restart the IGMP proxy process.
-```
