docs: reorganise -- current reference gathered, finished work archived, superseded and dead ideas marked as such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- docs/working/archive/superseded/: the Hermes-VM Tripod docs and July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  doc already flagged superseded or obsolete.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.

+Design doc for the word-level ACL (access control) system.
+
+- **[DESIGN.md](DESIGN.md)** — Full design: three ACL dispositions per word
+  (`STRICT`, `TTL`, `PINNED`), the four `DictEntry` fields (`acl_ttl`,
+  `acl_allow`, `acl_mode`, `acl_pinned`), the two VM flags
+  (`emergency_console`, `zuse_session`), and the implementation split between
+  C infrastructure and the pure-FORTH policy capsule `capsules/ACL.4th`.
+  Status: implemented through Phase 6 on `master`; Phase 7 (LithosAnanke
+  parity) is next.
+
+Implementation files referenced by this design: `capsules/ACL.4th`,
+`capsules/zuse.4th`, `src/word_source/acl_words.c`,
+`src/test_runner/modules/acl_words_test.c`, and the ACL proof set in
+`proof/` (`ACL_Pin_Monotone.thy`, `ACL_Inherit_Clears_Pin.thy`,
+`ACL_TTL_Bounded.thy`, `ACL_Emergency_Bypass.thy`, `ACL_No_Escalation.thy`).
