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.

-# Run VyOS in a Docker Container
-
-Docker is an open-source project for deploying applications as standardized
-units called containers. Deploying VyOS in a container provides a simple and
-lightweight mechanism for both testing and packet routing for container
-workloads.
-
-## IPv6 support for Docker
-
-VyOS requires an IPv6-enabled Docker network. Currently Linux distributions
-do not enable Docker IPv6 support by default. You can enable IPv6 support in
-two ways.
-
-### Method 1: Create a docker network with IPv6 support
-
-Here's an example using the `macvlan` driver.
-
-```none
-docker network create --ipv6 -d macvlan -o parent=eth0 --subnet 2001:db8::/64 --subnet 192.0.2.0/24 mynet
-```
-
-
-### Method 2: Add IPv6 support to the Docker daemon
-
-Edit /etc/docker/daemon.json to set the `ipv6` key to `true` and specify
-the `fixed-cidr-v6` to your desired IPv6 subnet.
-
-```none
-{
-  "ipv6": true,
-  "fixed-cidr-v6": "2001:db8::/64"
-}
-```
-
-Reload the Docker configuration.
-
-```none
-$ sudo systemctl reload docker
-```
-
-
-## Deploy container from ISO
-
-Download the ISO you want to base the container on. In this example,
-the ISO is `vyos-1.4-rolling-202308240020-amd64.iso`. If you
-created a custom IPv6-enabled network, include it as the `--net` parameter
-to `docker run`.
-
-```none
-$ mkdir vyos && cd vyos
-$ curl -o vyos-1.4-rolling-202308240020-amd64.iso https://github.com/vyos/vyos-rolling-nightly-builds/releases/download/1.4-rolling-202308240020/vyos-1.4-rolling-202308240020-amd64.iso
-$ mkdir rootfs
-$ sudo mount -o loop vyos-1.4-rolling-202308240020-amd64.iso rootfs
-$ sudo apt-get install -y squashfs-tools
-$ mkdir unsquashfs
-$ sudo unsquashfs -f -d unsquashfs/ rootfs/live/filesystem.squashfs
-$ sudo tar -C unsquashfs -c . | docker import - vyos:1.4-rolling-202111281249
-$ sudo umount rootfs
-$ cd ..
-$ sudo rm -rf vyos
-$ docker run -d --rm --name vyos --privileged -v /lib/modules:/lib/modules \
-> vyos:1.4-rolling-202111281249 /sbin/init
-$ docker exec -ti vyos su - vyos
-```
-
-To stop the container, run `docker stop vyos`.
