efiten cc37f9f689 fix(ci): stop cancelling master runs — only cancel stale PR builds (#1426) ...

## Summary

- `cancel-in-progress: true` was silently killing staging deploys
whenever a new commit landed on master during an active CI run
- During burst-merge sessions (7 cancelled runs documented in #1395),
staging drifted hours behind master with no failure signal (cancelled =
grey, not red)
- Fix: evaluate to `true` only for `pull_request` events, so PR branches
still drop stale runs but master runs always complete

## Test plan

- [ ] Verify expression evaluates correctly: PRs → `true` (cancel
stale), master push → `false` (never cancel), `workflow_dispatch` →
`false` (let manual runs complete)
- [ ] Manually trigger: merge 3 PRs in quick succession, confirm all 3
staging deploys complete
- [ ] Confirm no master CI run shows `cancelled` status after the fix

Closes #1395
