feat(#148): Implement Quality Orchestrator and Forced Continuation services

Browse Source 
Implements COORD-008 - Build Quality Orchestrator service that intercepts
completion claims and enforces quality gates.

**Quality Orchestrator (quality_orchestrator.py):**
- Runs all quality gates (build, lint, test, coverage) in parallel using asyncio
- Aggregates gate results into VerificationResult model
- Determines overall pass/fail status
- Handles gate exceptions gracefully
- Uses dependency injection for testability
- 87% test coverage (exceeds 85% minimum)

**Forced Continuation Service (forced_continuation.py):**
- Generates non-negotiable continuation prompts for gate failures
- Provides actionable remediation steps for each failed gate
- Includes specific error details and coverage gaps
- Blocks completion until all gates pass
- 100% test coverage

**Tests:**
- 6 tests for QualityOrchestrator covering:
  - All gates passing scenario
  - Single/multiple/all gates failing scenarios
  - Parallel gate execution verification
  - Exception handling
- 9 tests for ForcedContinuationService covering:
  - Individual gate failure prompts (build, lint, test, coverage)
  - Multiple simultaneous failures
  - Actionable details inclusion
  - Error handling for invalid states

**Quality Gates:**
✅ Build: mypy passes (no type errors)
✅ Lint: ruff passes (no violations)
✅ Test: 15/15 tests pass (100% pass rate)
✅ Coverage: 87% quality_orchestrator, 100% forced_continuation (exceeds 85%)
