Subject: [PATCH] chore(ci): introduce automerge-gate to aggregate
 path-filtered checks

Adds .github/workflows/automerge-gate.yaml so a single check
(`all-passed`) becomes the only required status, allowing checks
gated by `paths:` (e.g. actionlint) to be observed without blocking
PRs that don't trigger them.

Public mode is used so the gate's check_run is always posted, keeping
manual merges (no `auto_merge_enabled`, no approval) viable. The
follow-up operational step is to switch the branch ruleset's required
status checks from `build_and_test` + `commitlint` to `all-passed`.
