Add conventional-prefix branch patterns to on.push.branches so
CI triggers immediately on feat/**, fix/**, refactor/**, chore/**,
docs/**, perf/**, test/**, hotfix/** pushes без waiting for PR.
Side effects:
- Double-run при PR (push + pull_request events) — acceptable, capacity=2
- Не trigger'ит на experimental/wip/temp branches (no prefix) — intentional
