Resolves conflicts in VERSION (kept 0.19.0.0), package.json (kept 0.19.0.0),
and CHANGELOG.md (preserved 0.19.0.0 at top, inserted 0.18.4.0 below).
Main brought v0.18.4.0's codex + Apple Silicon hardening wave (PR #1056):
- Apple Silicon ad-hoc codesigning in ./setup (fixes SIGKILL on first run)
- /codex stdin deadlock fix (redirect from /dev/null)
- /codex + /autoplan preflight auth + version checks
- 10-minute timeout wrapper via gtimeout/timeout
- New bin/gstack-codex-probe consolidates auth/version/timeout logic
- test/codex-hardening.test.ts (25 unit tests, gate tier)
- test/setup-codesign.test.ts
- test/skill-e2e-autoplan-dual-voice.test.ts (periodic tier)
Auto-merged SKILL.md.tmpl updates across autoplan, codex, plan-ceo-review,
plan-eng-review, and the scripts/resolvers/{design,review}.ts modules.
None conflicted with v0.19's preamble refactor or new benchmark-models
skill — clean 3-way merge.
