test(01-09): RED — displaySurface:'monitor' + cursor:'always' constraint contract
Plan 01-09 Task 1 RED — pins 4 tests for D-15-display-surface contract:
1. getDisplayMedia called with strict {video:{displaySurface:'monitor',
cursor:'always'},audio:false} (deep-equality, NOT objectContaining).
2. Non-monitor pick (browser/window) tears down stream + emits
RECORDING_ERROR wrong-display-surface.
3. Monitor pick does NOT trip wrong-display-surface (over-fire guard).
4. classifyCaptureError routes 'wrong-display-surface' message prefix
to 'wrong-display-surface' code.
Task 2 will flip Tests 1, 2, 4 to GREEN by adding constraints +
post-grant validation + extending CaptureErrorCode union.
Deviation Rule 3: navigator getter-only in Vitest's node env required
Object.defineProperty wrapper (installNavigatorStub helper) instead
of direct assignment.
