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.

-# VPP Dataplane CPU Configuration
-
-VPP can utilize multiple CPU cores for better packet processing
-performance. Proper CPU configuration is essential for optimal
-throughput and low latency.
-
-VPP CPU assignment is handled automatically. You specify how many CPU
-cores VPP may use, and the system distributes them between the main
-thread and worker threads.
-
-:::{important}
-Review the system configuration settings page before changing CPU
-settings: {doc}`system`.
-:::
-
-If you don't configure CPU settings, VPP uses a single core for the
-main thread and doesn't create worker threads.
-
-## CPU Configuration Parameters
-
-### `cpu-cores`
-
-This parameter defines the total number of CPU cores allocated to VPP.
-
-```{cfgcmd} set vpp settings resource-allocation cpu-cores \<core-number\>
-```
-
-The system automatically assigns cores using the following rules:
-
-> - The first two CPU cores are always reserved for the operating system and
->   other services.
-> - The main VPP thread is assigned to the first available core after the
->   reserved ones.
-> - The remaining allocated cores are used for worker threads.
-
-For example:
-
-> - If cpu-cores is set to 1, VPP runs only a main thread.
->
-> - If cpu-cores is set to 4, VPP uses:
->
->   > - 1 core for the main thread
->   > - 3 cores for worker threads
-
-Choose a value based on available hardware resources and expected
-traffic load. Too few cores may limit performance, while too many can
-negatively impact other system services.
-
-## Potential Issues and Troubleshooting
-
-Improper CPU configuration can lead to issues such as:
-
-- VPP underperformance when not enough cores are assigned, or kernel
-  underperformance when too many cores are assigned to VPP.
-- Resource conflicts with other processes and services.
-
-Indicators of such issues are:
-
-- VPP or kernel forwarding performance is lower than expected
-- Degraded performance of system components or services, such as DNS,
-  DHCP, and dynamic routing
