test(packaging): keep exact uv_build pin contract upgrade-safe

[seonghobae]

Repository-owned CI defect exposed by #163

Dependabot PR #163 updates the exact uv_build pin from 0.12.1 to 0.12.3, but tests/test_packaging_metadata.py hard-coded the old version. Exact-head CI therefore installs successfully and then fails one repository-owned assertion despite the source retaining an exact uv_build==X.Y.Z pin.

This PR starts from protected main d4c54f4cabea289b48ad6050e52d6a86d284828b and changes only that contract test. It keeps the reproducibility requirement strict by requiring one exact semantic-version pin (uv_build==X.Y.Z) and explicitly rejecting range-based uv_build>=... requirements, while leaving the actual version authority in pyproject.toml where dependency update tooling can change it deliberately.

No production code, dependency version, lockfile, provider behavior, schema, credential, workflow, release authority, or protected-branch policy changes. This is independent of the Dependabot branch and avoids racing its pyproject.toml ownership.

Merge only on an unchanged exact head after current CI/security/central required workflows are terminal-success and review threads are clear.
