fix: auto-version-bump swallowed operator-direction; ptrmap + lock guards

- sf-db-schema.js: auto_vacuum INCREMENTAL → NONE. The "Bad ptr map entry"
  corruption on 2026-05-17 was incremental-autovacuum ptrmap drift under
  concurrent writers. Recovered DB has no ptrmap; future fresh DBs must
  match. incremental_vacuum() callers in sf-db-core.js become no-ops.
- bin/sf-from-source: lock allowlist extended to skip readonly sf headless
  subcommands (--help, query, status, usage, reflect, feedback list,
  triage --list/--json). Previously every sf headless invocation tried
  to acquire the project lock — operator couldn't even inspect SF state
  while autonomous was running.
- self-feedback.js triageBlockedEntries: (1) treat empty/null/undefined
  sfVersion as unknown, not zero; (2) exempt operator-direction kinds
  (improvement-idea, architecture-defect, missing-feature, gap) from
  auto-version-bump close. Both were needed to prevent the R124 incident
  recurring.
- headless-feedback.ts handleAdd: populate sfVersion via getCurrentSfVersion
  + detect repoIdentity via isForgeRepo, not hardcoded "external"/"". An
  empty sfVersion sorts below any real semver, so the resolver retry-closed
  every operator-filed entry within seconds.

Net effect: R124 proposal (filed via sf headless feedback add) is no
longer auto-resolved as version-stale. Larger architectural fix (single-
writer SF daemon / RPC for all DB writes — M040 territory) tracked as
follow-up R-entry.
