docs+ci+bot: complete post-PR#100 hygiene sweep across the estate

Human docs:
- AUDIT.adoc: move AUDIT-2026-05-20-A (Idris Types.idr) to Resolved; log the
  three unsound-axiom removals + six-prover completion; fix stale META.scm paths.
- CHANGELOG.md: Unreleased entries for the two-pillar completion, proofs CI,
  unsound-axiom fixes, Idris ABI repair.
- docs/{VERIFICATION_RESULTS,PROOF-COMPLETION-PLAN,PROOF-CLASSIFICATION}.adoc,
  docs/{proof-debt,proof-debt-triage}.md: dated status banners (historical
  content preserved; current state → PROOF-STATUS.adoc).
- docs/wiki/{Home,Proof-Systems,Verification,Roadmap,FAQ}.md: refresh proof
  numbers (11/11→14/14, +OND, +six provers), fix stale META.scm path.

Bot docs (.machine_readable/6a2/):
- AGENTIC.a2ml: correct dangerously-stale directives — lean4-sorry 18→0,
  coq-admitted 19→0; Lean/Idris now safe to edit; no-new-axiom rule.
- META.a2ml: ADR-011..014 (OND model, OND-1..5 landed, unsound removals,
  class-A acceptance); ADR-005 accepted.
- NEUROSYM.a2ml, PLAYBOOK.a2ml: refresh prover list + build/verify procedures.

CI:
- .github/workflows/proofs.yml: new — Coq (14 theories) + Z3 proof verification
  on PRs touching proofs/ (lightweight provers feasible on standard runners).

Note: docs/wiki (13 pages) is NOT published to the live GitHub wiki (a 1-line
stub, no sync workflow) — flagged for an owner decision, not pushed here.
