fix(ci): unblock docs-sync and release-please from CodeQL gate

[nsalvacao]

Summary

Two CI workflows were failing after every merge to main due to a branch protection ruleset that applied to ALL branches (~ALL) and required CodeQL results before any push — creating circular dependencies.

Root causes

Docs Sync — git-auto-commit-action pushed directly to main. The CodeQL branch protection rule blocks the push until CodeQL has run on that commit, but CodeQL can only run after the push. Circular dependency, not solvable without changing the architecture.

Release — release-please-action updates refs/heads/release-please--branches--main (its internal tracking branch). The ruleset's ~ALL condition applied CodeQL gate to ALL branches, including this release-please branch — making it impossible for release-please to function.

Fixes applied

Ruleset change (applied directly via GitHub API):

• Removed ~ALL from ruleset conditions — keeps only ~DEFAULT_BRANCH
• The CodeQL gate now only applies to main, not to every branch in the repo
• Unblocks release-please from managing refs/heads/release-please--branches--main

docs-sync.yml workflow change (this PR):

• Replaced git-auto-commit-action direct push with a PR-based approach
• Workflow creates a short-lived branch chore/docs-sync-<run_id>, commits, opens a PR, and enables auto-merge
• CodeQL runs on the PR branch, then auto-merge completes when checks pass
• No infinite loop: trigger paths (plugins/**, .claude-plugin/marketplace.json, scripts/sync-docs.py) don't include README.md or docs/ — merged commit won't re-trigger docs-sync

Test plan

• Merge this PR and confirm CodeQL passes on the PR branch
• Trigger workflow_dispatch on Docs Sync and verify it creates a PR with auto-merge
• Trigger a push to main that touches plugins/** and verify the full cycle completes
• Verify Release workflow passes on the next merge to main

Pull request overview

Updates the Docs Sync CI workflow to avoid direct pushes to main (which were blocked by CodeQL branch protection), by switching to a PR-based docs update flow.

Changes:

• Added pull-requests: write permission for the docs-sync job.
• Replaced direct auto-commit to main with: detect changes → create branch → push → open PR → enable auto-merge.

Review item	Decision	Technical rationale
[R1] Branch name uses only run_id — non-idempotent on rerun (Copilot inline, line 64)	Accepted	run_id is unique per run but reruns increment run_attempt; added -${{ github.run_attempt }} suffix so each attempt gets a unique ref. Prevents non-fast-forward push failures. Implemented.
[R2] PR creation/merge not robust on partial failure (Copilot inline, line 65-76)	Accepted with adaptation	If push succeeds but gh pr create fails mid-run, a rerun would attempt to create a PR for a branch that already exists. Fix: git checkout -B (force-reset existing branch), capture PR_NUMBER via gh pr view lookup before create, use number for gh pr merge. Copilot suggestion adopted; gh pr edit on existing PR omitted (branch is already unique per attempt, so reuse path is edge-case only). Implemented.
[CI1] Plugin Validation	No action needed	Passed on both commits. No workflow or plugin files changed.
[CI2] Security (OpenSSF Scorecard + CodeQL Python)	No action needed	Passed on both commits. Python files unchanged; YAML-only diff has no CodeQL findings.
[CI3] CodeQL (Copilot Advanced Security)	No action needed	Passed on both commits.
[CI4] GitGuardian Security Checks	No action needed	Passed on both commits. No secrets or credentials in diff.
