bundle files with dspy installation

[arnavsinghvi11]

fix for #7853 and #7490

ensures all github files are in the dspy installation package so runner.js can be recognized.

Tagging @chenmoneygithub for review on the proper pypi package installation.

Thanks for the PR! We should probably go with the following style to give us control over extra files to include instead of including everything:

[tool.setuptools]
packages = ["dspy"] 

[tool.setuptools.package-data]
"dspy" = ["primitives/*.js"]

I pushed a commit to explicitly list out the non-python files, testing result:

(always-clean) [package_bundling][~/Documents/mlflow_team/dspy/dist]$ ls dspy-2.6.6/dspy/primitives
__init__.py           module.py             python_interpreter.py
assertions.py         prediction.py         runner.js
example.py            program.py            tool.py

I can see the runner.js in the extracted directory.
