fix: fixed tool-call compatibility and tiny runtime resolver behavior

- Updated tool-call handling to accept string and object arguments.
- Stored object tool-call args directly into block.partialArgs and block.arguments.
- Added compiled runtime module resolution honoring exports, main, and index fallbacks.
- Patched tiny runtime loading to install resolver stubs and load the resolved entry file.
