GitHub Automation

Ryco keeps CI entrypoints small and routes shared checks through .github/workflows/_validation.yml.

• ci.yml validates main and manual CI runs with the full suite.
• branch-ci.yml validates non-main branch pushes with format, lint, typecheck, and tests. When the branch already has an open PR, branch CI skips expensive validation and lets PR validation own the ref.
• pull-request-validation.yml runs the full validation suite for PR review.
• worktree-validation.yml manually validates a worktree-backed ref and records the local worktree label/path in the run summary when provided.

Shared toolchain setup lives in .github/actions/setup-ryco, so new workflows should reuse that action instead of duplicating Bun, Node, cache, and install steps.
