Modify introspection / wrapper generation

Changes in these areas tend to cascade into dist/<ver>/abi/* outputs and may affect exported symbols.

Touch points

• Header scanning / AST extraction: introspect/

• Wrapper and export list generation: abi_exports/

• Symbol inventory / coverage: abi_impl/

• Build/link flags: app/CMakeLists.txt

Recommended workflow

1. Make your code change.

2. Rebuild a canary version with checks:

   python3 forge_cli.py build --version <mjver> --with-checks
   

3. Review dist/<ver>/abi/* diffs and ensure changes are intentional.

4. Update or add gates/tests if the contract changes.
