fix: address issues #153-#156 (App wf fallback, e2e hardening, ruleset strict=false, test additions) (#157)

* chore: add strong guard against unauthorized release PR merges

- Add label-based release guard step in auto-approve.yml (autorelease: pending)
- New scripts/guard-no-release-merge.sh hard-fail script for agents/humans
- Document 'Release PRs - Strong Guard' procedure + ask_user_question requirement in AGENTS.md
- Update tracking in patchloom-vscode-contrib skill (local only)

Prevents recurrence of agent running gh pr merge --auto on release-please PRs without explicit user yes.

All changes pass npm run check (259 tests, package ok).

* fix: address issues #153-#156 (App wf fallback, test hardening, ruleset strict=false, coverage tests)

- #153: auto-approve now falls back to GITHUB_TOKEN for auto-merge on wf-touching PRs (conditional App token creation); removes hard dependency on workflows:write grant.
- #154: added normalize/CRLF test case exercising pure helper in initializeProject.
- #155: bumped e2e managed/MCP timeouts to 60s for cold-start robustness.
- #156: updated live ruleset strict_required_status_checks_policy=false; release PRs now merge reliably when green.

Closes #153
Closes #154
Closes #155
Closes #156

All via npm run check (clean), double-checked, subagent reviewer passed (mostly ready, followed suggestions for full gate + draft PR flow).

* test: dedupe/rename normalize test per reviewer feedback (minor polish for #154)

+## Release PRs - Strong Guard
+
+Release PRs (created by release-please, titled "chore: release ..." or "chore(main): release ...", or labeled `autorelease: pending`) MUST NEVER be merged (with `gh pr merge`, `--auto`, or otherwise) without the user's explicit approval.
+
+Merging a release PR:
+- Publishes a new version of the VSIX
+- Creates git tags
+- Triggers the full release pipeline (Marketplace, Open VSX, attestation bundles)
+- The user controls release cadence, not the agent.
+
+### Required procedure (strong guard)
+
+When you encounter a release PR (during triage, gate check, `gh pr list`, or status):
+
+1. Report it clearly: "Release PR #N (vX.Y.Z) is ready to merge."
+2. Use the `ask_user_question` tool (or direct question) to ask: "Should I merge it?"
+3. **Only after receiving an explicit "yes" (or equivalent affirmative) from the user in this session**, proceed.
+4. Before executing any merge command, run the guard:
+   ```
+   bash scripts/guard-no-release-merge.sh <number>
+   ```
+   The script will abort with guidance unless `ALLOW_RELEASE_MERGE=yes` is set (only after user yes).
+5. If checks pass and user said yes: `gh pr merge <number> --squash` (or let auto if user directed).
+
+This rule was strengthened after an incident where `gh pr merge 144 --auto` (under a broad "merge everything" instruction) resulted in v0.0.5 being published without explicit per-release "yes".
+
+### Defense in depth
+
+- Workflow: `.github/workflows/auto-approve.yml` uses author + label check + wf-changes to never enable `--auto` for release PRs.
+- Script: `scripts/guard-no-release-merge.sh` provides a hard runtime guard for shell commands.
+- Documentation: This section + global AGENTS.md rule.
+- Branch protection + ruleset: still enforces checks, but does not replace user approval for releases.
+
+Never bypass the guard "just this once" or rationalize. Ask every time.
