name: Check branch/PR naming
description: |
  Validates that a PR's head branch and title follow the fritzlab naming
  standard. Always exits 0 — warn-only until the Bugs system is live.
  Produces WARN log lines for any violation.

  Standard:
    branch:   <role>/bug-<id>/<kebab>   e.g. dev/bug-x7k2m9/fix-terminal-resize
    chore:    chore/<kebab>              bug-less trivia only
    title:    [bug-<id>] Description    (chore PRs: no [bug-id] prefix)

  Role must be a roster handle: dev | ux | ops | security | perf | architect | support
  Break-glass: PRs authored by dfritz are exempt.
