feat(aphoria): implement programmatic extractors for Option<T> semantics
Completes Task #3 of httpclient dogfooding with 100% detection rate (7/7 violations).
## New Extractors
- **OptionBoundsExtractor**: Detects Option<T> fields set to None (unbounded)
- **OptionValueExtractor**: Extracts values from Some(n) for threshold checks
Both extractors use context-aware pattern matching to understand Rust Option<T>
semantics, which declarative extractors cannot handle.
## Implementation
**Files Created**:
- applications/aphoria/src/extractors/option_bounds.rs (257 lines)
- applications/aphoria/src/extractors/option_value.rs (277 lines)
- applications/aphoria/docs/examples/extractors/programmatic-option-semantics.md
**Files Modified**:
- applications/aphoria/src/extractors/mod.rs - Added module declarations
- applications/aphoria/src/extractors/registry.rs - Registered extractors
- applications/aphoria/dogfood/httpclient/.aphoria/claims.toml - Added 4 claims
- applications/aphoria/dogfood/httpclient/TASK-1-SUMMARY.md - Task #3 completion
## Results
| Metric | Value |
|--------|-------|
| Detection Rate | 100% (7/7 violations) |
| Improvement | +29 percentage points (from 71%) |
| New Violations | 2 (max_redirects, max_retries unbounded) |
| Unit Tests | 13 (all passing) |
## Two-Claim Strategy
For each bounded Option<T> field:
1. **configured** claim - Detects None (unbounded)
2. **max_value** claim - Validates Some(n) threshold
Example:
- `max_redirects: None` → CONFLICT (not configured)
- `max_redirects: Some(20)` → CONFLICT (exceeds 10)
- `max_redirects: Some(5)` → PASS
## Enterprise Quality
✓ Proper error handling (no unwrap/expect)
✓ Comprehensive tests (6+7 unit tests)
✓ Full documentation with examples
✓ Reusable for 10+ similar patterns
✓ Screening patterns for performance
## Cachewrap Dogfood
Also includes complete cachewrap dogfood exercise:
- 10 claims for Redis cache wrapper
- Day 1-5 summaries
- Full retrospective and evaluation
- Declarative extractors for all patterns
