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.

-Boot Steps
-**********
-
-VyOS 1.2 uses `Debian Jessie`_ as the base Linux operating system. Jessie was
-the first version of Debian that uses systemd_ as the default init system.
-
-These are the boot steps for VyOS 1.2
-
-1. The BIOS loads Grub (or isolinux for the Live CD)
-2. Grub then starts the Linux boot and loads the Linux Kernel ``/boot/vmlinuz``
-3. Kernel Launches Systemd ``/lib/systemd/systemd``
-4. Systemd loads the VyOS service file
-   ``/lib/systemd/system/vyos-router.service``
-5. The service file launches the VyOS router init script
-   ``/usr/libexec/vyos/init/vyos-router`` - this is part of the vyatta-cfg_
-   Debian package
-
-  1. Starts FRR_ - successor to `GNU Zebra`_ and Quagga_
-
-  2. Initialises the boot configuration file - copies over
-     ``config.boot.default`` if there is no configuration
-  3. Runs the configuration migration, if the configuration is for an older
-     version of VyOS
-  4. Runs The pre-config script, if there is one
-     ``/config/scripts/vyos-preconfig-bootup.script``
-  5. If the config file was upgraded, runs any post upgrade scripts
-     ``/config/scripts/post-upgrade.d``
-  6. Starts ``rl-system`` and ``firewall``
-  7. Mounts the ``/boot`` partition
-  8. The boot configuration file is then applied by ``/opt/vyatta/sbin/vyatta-boot-config-loader/opt/vyatta/etc/config/config.boot``
-
-    1. The config loader script writes log entries to
-       ``/var/log/vyatta-config-loader.log``
-
-  9. Runs ``telinit q`` to tell the init system to reload ``/etc/inittab``
-  10. Finally it runs the post-config script
-      ``/config/scripts/vyos-postconfig-bootup.script``
