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.

+# NMP example
+
+Consider how to quickly set up NMP and VyOS for monitoring.
+NMP is multi-vendor network monitoring from 'SolarWinds' built to
+scale and expand with the needs of your network.
+
+## Configuration 'VyOS'
+
+First prepare our VyOS router for connection to NMP. We have to set
+up the SNMP protocol and connectivity between the router and NMP.
+
+% stop_vyoslinter
+
+```none
+set interfaces ethernet eth0 address 'dhcp'
+set system name-server '8.8.8.8'
+set service snmp community router authorization 'test'
+set service snmp community router network '0.0.0.0/0'
+```
+
+% start_vyoslinter
+
+
+## Configuration 'NMP'
+
+Next, you should just follow the pictures:

+
+In the end, you'll get a powerful instrument for monitoring the VyOS systems.
