New ISA Checklist

Use this checklist before adding a second architecture backend:

1. Define an ArchitectureProfile for the ISA, including bit width, endianness, and extension set.
2. Define opcode and field tables for the ISA, including any extension / mode gating rules that affect decode legality.
3. Implement decoder-to-IR lowering against the shared DecodedInstruction surface instead of a string-first backend payload.
4. Add formatter coverage requirements:
   • Capstone-style text formatting
   • canonical text formatting
   • verbose debug formatting
   • structured JSON output
5. Add test assets:
   • golden fixtures
   • differential/oracle coverage
   • property tests
   • fuzz targets
6. Register benchmark cases for:
   • IR decode throughput
   • detail overhead
   • CLI end-to-end cost
7. Update README.md, README_CN.md, docs/support-matrix.md, and tests/differential/known-differences.toml as needed for the new ISA surface.
