Fix license references: MIT → Apache 2.0 (README + pyproject.toml)

[dgenio]

Bug

The LICENSE file at the repository root is Apache License 2.0, but the README.md states:

License

This project is licensed under the MIT License - see the LICENSE file for details.

Additionally, pyproject.toml contains an incorrect classifier:

"License :: OSI Approved :: MIT License"

Both the README and pyproject.toml are inconsistent with the actual Apache 2.0 LICENSE file.

Proposed fix

1. Update README.md

Update README.md license section from:

This project is licensed under the MIT License - see the LICENSE file for details.

to:

This project is licensed under the Apache License 2.0 - see the [LICENSE](LICENSE) file for details.

2. Update pyproject.toml classifier

Change:

"License :: OSI Approved :: MIT License",

to:

"License :: OSI Approved :: Apache Software License",

Why this matters

• License mismatches create legal ambiguity for users and contributors
• Automated compliance tools (FOSSA, Snyk, etc.) may flag the mismatch
• PyPI displays classifier-based license info — it currently shows MIT incorrectly
• The LICENSE file is the canonical source of truth; everything else must match

Labels to apply

• documentation
• priority:P2
• bug

Depends on

None — standalone micro-fix.

Acceptance criteria

• README.md license section references "Apache License 2.0" (not "MIT")
• pyproject.toml classifier updated from MIT to License :: OSI Approved :: Apache Software License
• LICENSE file remains unchanged (it is correct)
