fix(everyrow-mcp): add src package for hatchling wheel build (#4952)

## Summary

- Adds `src/everyrow_mcp/__init__.py` to the `everyrow-mcp` stub so
hatchling can build the wheel (was missing, causing PyPI publish to
fail)
- Adds `[tool.hatch.build.targets.wheel] packages =
["src/everyrow_mcp"]` to match the `everyrow` stub pattern

All 4 packages build successfully locally.
