docs(vault): de-stale the quant and swap method pages

Parent-written (scout summaries were corroborated against the files, not
trusted): every restatement of an endpoint shape now cites the endpoint page,
and four claims contradicted by today's fleet state are corrected.

- Quantization Production: the challenger-contract line quoted the retired
  compaction-hub window; now cites [[frank-zealot]]'s Current shape. The 3090
  worked example is era-tagged. Sources listed [[frank-dragoon]] three times.
- Quantization by Hardware Architecture: said the 3090 lives on Dankserver
  (it moved to Dankclaw 2026-09-16; the Eras table owns the move) and ranked
  the retired Ling-3.0 Quark INT4 service as the ACTIVE Dankclaw workload. The
  active service is [[frank-dragoon]] on a closed `.hgn` format.
- GGUF Compatibility: Related claimed the ftype-115 ROCmFPX file was "in
  production"; that is an era now, so it points at [[kingjones-q8agent-rocmfpx]].
- Model Swap and Rollback: dropped the fragment byte-count ledger (AGENTS.md
  owns it), the Ampere FP8 hardware claim ([[Quantization by Hardware
  Architecture]] owns it), halogen's HTTP surface ([[frank-dragoon]]'s wire
  contract) and three brittle unit-file line refs (accepted loss: line numbers
  are derivable, the root-unit law stays). Fixed the per-slot example, which
  described the retired 3-slot arithmetic, and a Related bullet that called
  [[frank-archon]] retired while linking the same page twice.

Census over the diff: 1 orphan line, the deleted unit line-number refs above.
