fix: include template files in package installation

codemcp/templates/ contains data files that aren't Python files per se, but they need to be installed properly so that they're available to be copied when we run codemcp init. Fix pyproject.toml so that we correctly include the data files. I think I want to recursively glob everything that isn't excluded by .gitignore, but if it's best practice to directly only package things that are Git versioned that would work too (not sure how you gonna do source tarballs that way though.)
