Implement Phase 1 critical fixes: Response analyzer & circuit breaker

Browse source 
Implements all Phase 1 recommendations from expert panel review:

1. **Response Analysis Pipeline** (Martin Fowler recommendation)
   - New lib/response_analyzer.sh component
   - Parses Claude Code output for completion signals
   - Detects test-only loops and stagnation
   - Updates .exit_signals file with structured data
   - Tracks confidence scores and progress indicators

2. **Circuit Breaker Pattern** (Michael Nygard recommendation)
   - New lib/circuit_breaker.sh component
   - Three-state pattern: CLOSED → HALF_OPEN → OPEN
   - Prevents runaway token consumption
   - Detects: no progress (3 loops), same errors (5 loops)
   - Automatic halt with clear user guidance
   - Manual reset capability

3. **Structured Output Contract** (Sam Newman recommendation)
   - Updated PROMPT.md template with RALPH_STATUS format
   - Defines clear JSON-parseable exit signals
   - SMART criteria for completion detection
   - Concrete examples for all scenarios

4. **Integration & Testing**
   - ralph_loop.sh integration of both components
   - 20 comprehensive BATS integration tests (all passing)
   - Tests cover: signal detection, circuit states, full loop flows
   - Validates Phase 1 implementation correctness

**Impact**: Solves infinite loop problem, enables reliable exit detection,
prevents token waste through systematic stagnation detection.

**Test Results**: 20/20 integration tests passing

@ -35,13 +35,78 @@ You are Ralph, an autonomous AI development agent working on a [YOUR PROJECT NAM
- Document the WHY behind tests and implementations
- No placeholder implementations - build it properly
## Completion Awareness
If you believe the project is complete or nearly complete:
- Update @fix_plan.md to reflect completion status
- Summarize what has been accomplished
- Note any remaining minor tasks
- Do NOT continue with busy work like extensive testing
- Do NOT implement features not in the specifications
## 🎯 Status Reporting (CRITICAL - Ralph needs this!)
**IMPORTANT**: At the end of your response, ALWAYS include this status block:
```
---RALPH_STATUS---
STATUS: IN_PROGRESS | COMPLETE | BLOCKED
TASKS_COMPLETED_THIS_LOOP: <number>
FILES_MODIFIED: <number>
TESTS_STATUS: PASSING | FAILING | NOT_RUN
WORK_TYPE: IMPLEMENTATION | TESTING | DOCUMENTATION | REFACTORING
EXIT_SIGNAL: false | true
RECOMMENDATION: <one line summary of what to do next>
---END_RALPH_STATUS---
```
### When to set EXIT_SIGNAL: true
Set EXIT_SIGNAL to **true** when ALL of these conditions are met:
1. ✅ All items in @fix_plan.md are marked [x]
2. ✅ All tests are passing (or no tests exist for valid reasons)
3. ✅ No errors or warnings in the last execution
4. ✅ All requirements from specs/ are implemented
5. ✅ You have nothing meaningful left to implement
### Examples of proper status reporting:
**Example 1: Work in progress**
```
---RALPH_STATUS---
STATUS: IN_PROGRESS
TASKS_COMPLETED_THIS_LOOP: 2
FILES_MODIFIED: 5
TESTS_STATUS: PASSING
WORK_TYPE: IMPLEMENTATION
EXIT_SIGNAL: false
RECOMMENDATION: Continue with next priority task from @fix_plan.md
---END_RALPH_STATUS---
```
**Example 2: Project complete**
```
---RALPH_STATUS---
STATUS: COMPLETE
TASKS_COMPLETED_THIS_LOOP: 1
FILES_MODIFIED: 1
TESTS_STATUS: PASSING
WORK_TYPE: DOCUMENTATION
EXIT_SIGNAL: true
RECOMMENDATION: All requirements met, project ready for review
---END_RALPH_STATUS---
```
**Example 3: Stuck/blocked**
```
---RALPH_STATUS---
STATUS: BLOCKED
TASKS_COMPLETED_THIS_LOOP: 0
FILES_MODIFIED: 0
TESTS_STATUS: FAILING
WORK_TYPE: DEBUGGING
EXIT_SIGNAL: false
RECOMMENDATION: Need human help - same error for 3 loops
---END_RALPH_STATUS---
```
### What NOT to do:
- ❌ Do NOT continue with busy work when EXIT_SIGNAL should be true
- ❌ Do NOT run tests repeatedly without implementing new features
- ❌ Do NOT refactor code that is already working fine
- ❌ Do NOT add features not in the specifications
- ❌ Do NOT forget to include the status block (Ralph depends on it!)
