a3eb5cbf27 docs: Add comprehensive V2G EXI implementation documentation
- Add DECODE.md: Complete decoding analysis with message structure details
- Add ENCODE.md: Complete encoding analysis with bit-level implementation
- Add V2G_IMPLEMENTATION_GUIDE.md: Developer guide with step-by-step implementation

Key features:
- Byte-by-byte analysis of test5.exi (43 bytes) with bit structure
- Complete Grammar State Flow documentation for all message types
- PhysicalValue encoding/decoding with exact bit patterns
- BitStream implementation guide with writeBits/readBits functions
- 18 V2G message types with Body Choice mapping (0-21)
- Implementation phases and debugging guidelines
- 100% VC2022 compatibility achievements documented

Technical details:
- EXI header structure (0x80 + 0x98 pattern explanation)
- SessionID BINARY_HEX encoding (8-byte compression)
- Grammar transitions (273→274→275→276→277→278→280→281→282→3)
- Choice bit calculations (3-bit, 2-bit, 1-bit selections)
- Integer16 encoding with sign bit + variable length magnitude
- Complete CurrentDemandReq/Res implementation examples
