Phase 2: Requirements, testing, and documentation enhancements

Implements all Phase 2 high-priority recommendations from expert panel:

**1. Requirements Improvement** (Karl Wiegers, Gojko Adzic)
- Enhanced templates/PROMPT.md with 6 concrete Given/When/Then scenarios
- Specification by Example format for all exit conditions
- Clear expectations for each scenario type:
  * Successful completion
  * Test-only loops
  * Stuck on errors
  * No work remaining
  * Making progress
  * Blocked on dependencies

**2. Use Case Documentation** (Alistair Cockburn)
- Created comprehensive USE_CASES.md (600+ lines)
- Defined 6 primary use cases with full Cockburn format:
  * UC-1: Execute Development Loop
  * UC-2: Detect Project Completion
  * UC-3: Prevent Resource Waste
  * UC-4: Handle API Rate Limits
  * UC-5: Provide Loop Monitoring
  * UC-6: Reset Circuit Breaker
- Includes actors, goals, success scenarios, extensions, edge cases
- Clear goal hierarchy and success metrics

**3. Enhanced Test Coverage** (Lisa Crispin, Janet Gregory)
- Added tests/integration/test_edge_cases.bats (20 new tests)
- Edge cases: empty files, large files, corrupted JSON, unicode
- Boundary conditions: exact thresholds, overflow scenarios
- Error conditions: missing git, malformed data, rapid transitions
- All 40 integration tests passing (100% success rate)

**4. Circuit Breaker Robustness**
- Enhanced init_circuit_breaker() with corruption detection
- Auto-recovery from corrupted state/history files
- Validates JSON before use, recreates if invalid

**5. Specification Workshop Guide**
- Created SPECIFICATION_WORKSHOP.md
- Three Amigos methodology with templates
- Includes complete example workshop
- Best practices and red flags
- Quick 15-minute template for small features

**Test Results**: 40/40 integration tests passing
**Documentation Added**: 1,200+ lines (USE_CASES.md, SPECIFICATION_WORKSHOP.md)
**Coverage Improvement**: Edge cases and error conditions fully tested
