Trilltechnician de9dcda1f7 feat: Phase 2 & 3 - RTL_433 integration + RAW timing analysis
Phase 2: RTL_433 Protocol Matcher (286 devices)
================================================
Created src/matcher/rtl433_matcher.py
- RTL433Matcher class with JSON database loader
- Built search indexes: device_id, name, category, modulation
- Fuzzy matching with difflib.SequenceMatcher (>0.6 similarity)
- Timing signature matching (±15% tolerance)
- Confidence scoring:
  * Exact ID match: 0.95
  * Exact name match: 0.90
  * Fuzzy match: 0.70-0.85
  * Timing match: 0.70-0.95
- Singleton pattern for performance

Phase 3: RAW Signal Timing Analysis
====================================
Created src/parser/raw_parser.py
- RAWParser class for Flipper Zero RAW_Data format
- TimingSignature dataclass with pulse analysis
- Extracts short_pulse, long_pulse, gap, pulse_ratio
- Percentile-based clustering (25th/75th)
- Encoding detection (PWM, PPM, Manchester, OOK)
- Statistical analysis (mean, std, total duration)

Integration & Enhancements
===========================
Enhanced src/matcher/simple_matcher.py
- Added raw_data parameter to match() method
- RTL_433 protocol matching (Phase 2) with logging
- Timing analysis for RAW captures (Phase 3)
- Graceful degradation with try/except
- RTL433_AVAILABLE flag for feature detection
- Maintains backward compatibility

Updated src/api/main_simple.py
- Extract raw_data from parsed metadata
- Convert List[int] to space-separated string
- Pass raw_data to enhanced matcher

Validation Results
==================
Test script: test_enhanced_matcher.py
- 20 existing captures re-matched
- 4 captures improved (20%)
- 0 captures worse (0%)
- Average improvement: +0.16 confidence
- Best improvement: +0.35 (MegaCode → Linear Megacode)
- RTL_433 exact match: MegaCode → 0.95 confidence
- RTL_433 fuzzy match: Princeton → Insteon 0.79

Expected Accuracy
=================
- Phase 2 alone: 75-80% (+15%)
- Phase 2 + 3: 80-85% (+20-25%)
- Current validation: Phase 2 confirmed working
- Phase 3: Requires new uploads with raw_data

Deployment Ready
================
- Backward compatible (optional raw_data)
- No breaking changes to API
- Graceful import fallback
- Ready for server deployment
