v1.2.4 — fix: bypass marker grep

Maintenance patch backport.

What's fixed

Single commit backport of #39 onto the v1 line: the escape-hatch grep at the verdict-check step now correctly matches the documented `[skip-claude-review: reason]` form advertised in every error message. The prior fixed-string pattern only matched the bare `[skip-claude-review]` token that wasn't documented anywhere.

See AAR 2026-04-17 for the real-world bite this fixes — three consecutive `gh run rerun` attempts in one session wasted CI budget because the bypass marker users were typing (`[skip-claude-review: infrastructure flake]`) never matched the grep.

Consumer action

If you're pinned to `@v1` — none. The floating `v1` tag advances to this release automatically.

If you're pinned to a specific older tag (`@v1.2.3`, etc.) — update to `@v1.2.4` or `@v1` to pick up the fix.

Future

This is likely the final v1.x release. The v1 → v2 migration path is documented in the v2.0.0 release notes.
