Crate light_instruction_decoder 

Instruction decoder library for Light Protocol.

This crate provides:

• Core types for instruction decoding (DecodedField, DecodedInstruction, InstructionDecoder trait)
• Decoder registry for managing multiple program decoders
• Built-in decoders for Light Protocol programs (System, Compressed Token, etc.)
• Transaction logging configuration and formatting utilities

The crate is designed to be independent of LiteSVM/test infrastructure, enabling use in both test environments and standalone tools.

Note: Most functionality is only available off-chain (not on Solana targets).
