## Summary
- Split the monolithic `test_helper.ts` (~1700 lines) into focused
modules for better maintainability
- Created `constants.ts` for timeout constants
- Created `fixtures.ts` for Playwright fixtures and test setup
- Created `utils/` directory for utility functions (normalization,
dump-prettifier)
- Created `page-objects/` directory with component and dialog page
objects

## Test plan
- [x] All existing unit tests pass (784 tests)
- [x] Lint and type checks pass
- [ ] E2E tests should work with the refactored helpers (imports are
re-exported from test_helper.ts for backward compatibility)

## Summary by cubic
Refactored e2e test helpers into modular page objects, fixtures, and
utilities for easier maintenance and more deterministic snapshots. Added
loop guards to prevent hangs in toast dismissal and the Context Files
Picker; existing tests keep working via re-exports.

- **Refactors**
- Split test_helper.ts into constants.ts, fixtures.ts, utils/, and
page-objects/ (components + dialogs); added a main PageObject that
composes component page objects.
- Introduced normalization and dump-prettifier utilities for stable
snapshots.
- Centralized CI-aware timeouts in constants.ts; added optional debug
logging flag.
  - Kept test_helper.ts as a thin re-export for backward compatibility.
- Updated TypeScript strict-mode docs with ES2020 target limitations on
replaceAll.

- **Bug Fixes**
  - Fixed importApp path resolution to use __dirname three levels up.
- Switched git config calls to execFileSync to avoid command injection.
- Corrected toast dismissal loop to click the first toast repeatedly
until none remain; added maxAttempts=20 guard (and in Context Files
Picker) to prevent hangs.
- Derived the app executable name from appInfo instead of hardcoding
dyad.exe.
