Subject: [PATCH] perf(ci): concurrency groups + strict pnpm lockfile
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Iteration 1 — CI reliability and speed:
- Concurrency: cancel in-progress CI runs when new push arrives
  to the same branch. Why: Avoids waste when pushing multiple
  fixes in quick succession; only the latest code is tested.
- pnpm: switch from --no-frozen-lockfile to --frozen-lockfile.
  Why: Fails fast if pnpm-lock.yaml is outdated — prevents
  untested dependency changes from reaching main.
- pnpm: add --prefer-offline to use locally cached packages.
  Why: Slightly faster installs when packages are already
  available in the runner image cache.
