Bump version to 3.0.1 and clean up README formatting

[goldlabelapps]

This pull request updates the project version and branding, simplifies the root API endpoint, and makes minor improvements to the README.md for clarity and consistency.

Branding and Version Updates:

• Updated the project name and branding from "Python" to "Python°" throughout the codebase and documentation, including the docstring in app/__init__.py and the root endpoint metadata in app/api/root.py. [1] [2]
• Bumped the project version from 1 to 3.0.1 in app/__init__.py.

API Endpoint Response Simplification:

• Simplified the root endpoint (/) in app/api/root.py to only return metadata, removing the detailed list of endpoints from the response.

Documentation Improvements:

• Updated section headers in README.md for consistency (e.g., "Project Overview" to "Overview", "🚀 Features" to "Features").
• Minor formatting and whitespace cleanups in README.md for readability. [1] [2]

This changes the GET / response shape by removing the "data" key. The repo’s tests (tests/test_routes.py) currently assert that "data" is present in the root response, so this will fail CI and may also break existing clients expecting a consistent {meta, data} envelope. Either keep returning a "data" field (e.g., an empty list/object) or update the test/clients as part of this PR.

Suggested change

	return {"meta": meta}
	return {"meta": meta, "data": {}}

[Copilot]

The root endpoint’s meta payload is diverging further from the project’s standard meta format: most routes use app.utils.make_meta(), which includes keys like severity and base (not base_url). Dropping "severity" and using "base_url" here makes meta inconsistent across endpoints and complicates client handling; consider using make_meta("success", ...) (and/or aligning key names) for consistency.

	"version": __version__,
