HYDI-34: Phase 3: Tests for monitor state machine and merged-PR transition

[kasperwelner]

Implements HYDI-34

Changes

• Expanded src/orchestration/monitor.test.ts with focused branch coverage for checkRuns and merged-PR sweep behavior, including:
  • no-running-runs path, missing run_id, SUCCEEDED/FAILED/ERROR/CANCELLED/INPROGRESS/BLOCKED flows
  • In Review transition best-effort behavior and fallback error handling
  • merged-PR sweep paths for missing PR URL, done-status skip, parse failures, merge/no-merge transitions, missing Done transition, and GitHub errors
  • outer-loop resilience when Oz retrieve fails
• Added vi.resetModules() in beforeEach to guarantee clean singleton state per test (_ozClient, _githubClient).
• Re-indented the inner checkRuns try / else if chain in src/orchestration/monitor.ts for visual brace alignment with no behavior change (git diff -w -- src/orchestration/monitor.ts is clean).

Validation

• npm test
• npm run test:coverage (monitor.ts coverage: 87.45% statements, 84.81% branches)
• npm run typecheck
