Closes #407
This PR adds AST-based validation for undeclared state reads in
function-based actions.
### What this does
- Parses the originating function using `inspect.getsource`
- Walks the AST to detect `state["<literal>"]` accesses
- Compares detected keys with declared `reads=[...]`
- Raises `ValueError` if undeclared keys are accessed
- Skips validation when source is unavailable
### Why
Prevents silent bugs caused by accessing state keys that were not declared
in `reads`, enforcing stricter action correctness.
### Tests
- Added unit tests covering:
- Valid declared reads
- Undeclared read detection
