docs: reorganise -- current reference gathered, finished work archived, superseded and dead ideas marked as such

docs/CLAUDE.md Phase 2, 2026-10-14.  All moves by git mv; every archived
file carries a header saying what it is, why, and where to look instead.

- docs/reference/ (new): roadmap and versioning policy, M7.1, word-ACL
  design, kernel args, hosted acceptance test, dictionary, primitives,
  ontology, L8 table -- previously spread over docs/, docs/lithosananke/
  and docs/03-architecture/.
- docs/working/archive/historical/: finished work (session plan, test-gap
  audit, birthing plan, fix write-ups, the January architecture draft).
- docs/working/archive/superseded/: the Hermes-VM Tripod docs and July
  Hermes designs (-> FABRIC-3.5/3.6), the StarForth roadmap, every working
  doc already flagged superseded or obsolete.
- docs/working/archive/dead/: the hal_* target contract (never adopted),
  L4Re, metrics-and-knobs.
- Papers and proposals into docs/working/papers/.
- References rewritten across the repo (not logs/, not docs/patent/);
  CLAUDE.md's documentation section rewritten.
