Christian Byrne 033b3dad3a feat: add Slack notification workflow for coverage improvements (#10977)
## Summary

Adds a GitHub Actions workflow + TypeScript script that posts to Slack
when a merged PR improves unit or E2E test coverage.

## Changes

- **What**: New `coverage-slack-notify.yaml` workflow triggered on push
to main. Compares current coverage against previous baselines, generates
Slack Block Kit payload with progress bars and milestone celebrations,
posts to `#p-frontend-automated-testing`.
- **Script**: `scripts/coverage-slack-notify.ts` — parses lcov files,
computes deltas, detects milestone crossings (every 5%), builds Slack
payload. Pure functions exported for testability.
- **Tests**: 26 unit tests in `scripts/coverage-slack-notify.test.ts`
covering all pure functions including edge cases (malformed lcov, exact
boundaries, zero coverage).

### Security hardening
- All `${{ }}` expressions moved from `run:` blocks to `env:` variables
- `SLACK_BOT_TOKEN` passed via env var, not inline
- Unique heredoc delimiter (timestamp-based) prevents payload injection
- `parseInt` fallback (`|| 0`) guards against malformed lcov
- PR regex anchored to first line of commit message

### Robustness
- `continue-on-error: true` on Slack post step (outage does not fail the
job)
- Baseline save guarded by `steps.unit-tests.outcome == success`
(prevents corrupt baselines on test failure)
- Channel ID commented for maintainability
- Top-level `text` field added for Slack mobile push notifications
- Author linked to GitHub profile instead of bare `@username`

## Review Focus

- Workflow step ordering and conditional logic
- Security of expression handling and secret management
- Slack payload structure and Block Kit formatting
