tegwick e7bafd69fc feat(local-identity): Stage 4 — security hardening (NK-WP-0002-T04)

Permission enforcement on startup: enforce_permissions() checks store dir
(700), user files (600), signing key, TLS key, audit.log, revoked.json.
CLI and run_server() call it before any sensitive operation.

New modules:
  security.py  check_store(), enforce_permissions(), print_security_check()
  audit.py     log_event() — append-only TSV audit log (mode 600)
  revoke.py    revoke(jti), is_revoked(jti) — revocation list (mode 600)

New CLI commands:
  security-check          Print per-check pass/warn/fail report; exit 1 on failure
  revoke-token <jti|jwt>  Add JTI to revocation list; accepts raw JTI or full JWT

Serve integration:
  Audit log written for auth request, token issuance, and userinfo calls
  Revocation checked at /userinfo; revoked tokens return 401

Docs: security model section in LocalIdentity.md — threat model,
assumptions, non-guarantees, SELinux/AppArmor guidance, revocation usage.

138 tests passing (34 new for Stage 4).
