Subject: [PATCH] ci: restore CodeQL code scanning workflow

The GitHub-managed default code scanning setup was turned off
(default-setup = not-configured), so no analysis runs to re-evaluate
alerts. The 13 open 'actions/missing-workflow-permissions' alerts were
already fixed by #211 but stay open with nothing to close them.

Add an advanced-setup CodeQL workflow (actions + javascript-typescript)
so a run on main re-scans the now-hardened workflows and auto-closes the
stale alerts. The workflow itself follows least privilege:
top-level permissions {} plus narrow per-job grants.
