refactor(phase-91): Modularize P5b escape pattern recognizer
### Changes
#### 1. New Module: escape_pattern_recognizer.rs (255 lines)
- Dedicated module for P5b (Escape Sequence Handling) pattern
- Single Responsibility Principle: handles only escape pattern detection
- Clean interface: exports only `detect_escape_skip_pattern()` and `EscapeSkipPatternInfo`
- Private helpers for pattern-specific analysis
**Moved functions**:
- `detect_escape_skip_pattern()` - main recognizer
- `find_break_in_if()` - break detection
- `find_escape_in_if()` - escape check detection
- `extract_delta_pair_from_if()` - delta extraction
- `try_extract_increment_assignment()` - increment parsing
#### 2. ast_feature_extractor.rs (1046 lines, was 1345)
- Removed deprecated `extract_escape_delta_from_if()` function
- Removed P5b-specific implementation (moved to escape_pattern_recognizer)
- Added re-export for backward compatibility
- **Result**: 299 lines removed (77% of original), cleaner focus on general pattern analysis
#### 3. mod.rs (patterns/)
- Registered new `escape_pattern_recognizer` module
- Updated documentation to reflect modularization
### Results
✅ **File Size Reduction**: 1345 → 1046 lines in ast_feature_extractor
✅ **Code Organization**: Single-responsibility modules
✅ **Reusability**: P5b helpers isolated for Phase 92+ reuse
✅ **Test Status**: 1062/1062 tests PASS (no regressions)
✅ **Dead Code**: Removed deprecated function
### Architecture Improvement
**Before**:
```
ast_feature_extractor.rs (1345 lines)
├─ Generic pattern detection (detect_continue, detect_parse_*, etc.)
└─ P5b-specific helpers (deeply nested, hard to navigate)
```
**After**:
```
ast_feature_extractor.rs (1046 lines) - Generic patterns only
escape_pattern_recognizer.rs (255 lines) - P5b-specific, organized
├─ Main recognizer
└─ Focused private helpers
```
### Next Steps
- Phase 92: Implement JoinIR lowering for P5b using this recognizer
- Phase 93: Pattern P5 (guard-bounded) detection
Boxification/modularity complete! 🎉
