Add Python wrapper proof-of-concept (TestPyPI) for #82

[stephenredhat]

Description

Adds a small, stdlib-only Python wrapper for the disclosure CLI under a new python/ dir, so it's installable via pip/uvx and importable from notebooks. Per @andrew's suggestion it distributes the prebuilt binary (downloads on first use, verifies against checksums.txt, caches, shells out) rather than building an FFI binding. Provides a CLI passthrough (disclosure scan ...) and a small library API (scan()/text()/version() return parsed JSON). No changes to the Go tool. Intended for TestPyPI first.

This PR fixes #82

Notes for Reviewers

• Deliberately a PoC — alpha, stdlib-only, one universal wheel; wrapped binary version pinned via DISCLOSURE_VERSION.
• Treats CLI exit code 1 (AI detected) as success; only ≥2 raises. Covered by a test.
• Open questions: python/ here vs a separate repo? license -only vs -or-later? PyPI name disclosure vs disclosure-cli?
• Tested: go build/go test pass unchanged; pytest (6) passes; verified end-to-end against a local v1.0.0 binary.

@stephenredhat regarding your open questions above:

Open questions: python/ here vs a separate repo? license -only vs -or-later? PyPI name disclosure vs disclosure-cli?

I think the separate python/ folder in this repo with all the wrapper code (like in this PR) is good enough. For license, I'd prefer if we keep -or-later since it's more future-compatible than -only. Regarding PyPI name, can we name it disclosure-py? So we follow standard python wrapper naming conventions :)

Thanks @andrew , fixed all three in the latest commit

@omkar-foss Thanks, Ill keep it in the python folder and name it disclosure-py. On the license I've matched what the repo already use for now
