fix(coordinode): move package into coordinode/ subdirectory for correct wheel build

hatchling's packages = ["coordinode"] requires a coordinode/ subdirectory.
Previously __init__.py and other modules were co-located with pyproject.toml,
making the project root the package root — unsupported by hatchling.

Move __init__.py, client.py, _types.py → coordinode/coordinode/
Update pyproject.toml: version-file path, revert sources → packages
Update Makefile: PROTO_OUT points to coordinode/coordinode/_proto/
Update .gitignore: adjusted paths for generated files

The resulting wheel now correctly contains coordinode/__init__.py
and all submodules, making the package importable after pip install.
