Implement Phase 1 tasks 1.5-1.7 + 1.9 (Codec 8/8E/16 parsers + fixture suite)

Browse Source 
- Codec 8 parser (1-byte IO IDs, no NX/Generation Type)
- Codec 8 Extended parser (2-byte IO IDs + variable-length NX section)
- Codec 16 parser (mixed widths + Generation Type, supports IO IDs > 255)
- Shared GPS element / timestamp helpers in gps-element.ts
- Fixture loader with bigint/Buffer sentinel encoding and auto-discovery
- 12 fixture pairs across codec8/8E/16 (canonical doc + synthetic edge cases)
- Cross-checked Codec 8 against Traccar's TeltonikaProtocolDecoder (no discrepancies)

26 new tests. Total 62 passing across 10 test files.
typecheck/lint/test/build all clean.
