* fix: remove auth token from /health, secure extension bootstrap (CRITICAL-02 + HIGH-03)
- Remove token from /health response (was leaked to any localhost process)
- Write .auth.json to extension dir for Manifest V3 bootstrap
- sidebar-agent reads token from state file via BROWSE_STATE_FILE env var
- Remove getToken handler from extension (token via health broadcast)
- Extension loads token before first health poll to prevent race condition
* fix: require auth on cookie-picker data routes (CRITICAL-01)
- Add Bearer token auth gate on all /cookie-picker/* data/action routes
- GET /cookie-picker HTML page stays unauthenticated (UI shell)
- Token embedded in served HTML for picker's fetch calls
- CORS preflight now allows Authorization header
* fix: add state file TTL and plaintext cookie warning (HIGH-02)
- Add savedAt timestamp to state save output
- Warn on load if state file older than 7 days
- Auto-delete stale state files (>7 days) on server startup
- Warning about plaintext cookie storage in save message
* fix: innerHTML XSS in extension content script and sidepanel (MEDIUM-01)
- content.js: replace innerHTML with createElement/textContent for ref panel
- sidepanel.js: escape entry.command with escapeHtml() in activity feed
- Both found by security audit + Codex adversarial red team
* fix: symlink bypass in validateReadPath (MEDIUM-02)
- Always resolve to absolute path first (fixes relative path bypass)
- Use realpathSync to follow symlinks before boundary check
- Throw on non-ENOENT realpathSync failures (explicit over silent)
- Resolve SAFE_DIRECTORIES through realpathSync (macOS /tmp → /private/tmp)
- Resolve directory part for non-existent files (ENOENT with symlinked parent)
* fix: freeze hook symlink bypass and prefix collision (MEDIUM-03)
- Add POSIX-portable path resolution (cd + pwd -P, works on macOS)
- Fix prefix collision: /project-evil no longer matches /project freeze dir
- Use trailing slash in boundary check to require directory boundary
* fix: shell script injection in gstack-config and telemetry (MEDIUM-04)
- gstack-config: validate keys (alphanumeric+underscore only)
- gstack-config: use grep -F (fixed string) instead of -E (regex)
- gstack-config: escape sed special chars in values, drop newlines
- gstack-telemetry-log: sanitize REPO_SLUG and BRANCH via json_safe()
* test: 20 security tests for audit remediation
- server-auth: verify token removed from /health, auth on /refs, /activity/*
- cookie-picker: auth required on data routes, HTML page unauthenticated
- path-validation: symlink bypass blocked, realpathSync failure throws
- gstack-config: regex key rejected, sed special chars preserved
- state-ttl: savedAt timestamp, 7-day TTL warning
- telemetry: branch/repo with quotes don't corrupt JSON
- adversarial: sidepanel escapes entry.command, freeze prefix collision
* chore: bump version and changelog (v0.13.1.0)
