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.

+## Configuration Blueprints (autotest)
+
+The next pages contain fully automated configuration examples.
+
+Each lab will build and test from an external script.
+The page content is generated, so changes will not take effect.
+
+A host `vyos-oobm` will be used as an SSH proxy. This host is just
+necessary for the lab tests.
+
+The process will do the following steps:
+1. create the lab on a eve-ng server
+2. configure each host in the lab
+3. do some defined tests
+4. optional do an upgrade to a higher version and do step 3 again.
+5. generate the documentation and include files
+6. shutdown and destroy the lab, if there is no error
