chore(deps): bump build from 1.6.0 to 1.6.1

[dependabot]

Release lock repair

Regenerated requirements/release.txt with uv 0.12.15 using the documented universal Python 3.11 target. Relative to main, only build 1.6.0 -> 1.6.1 and its hashes change. Windows dependencies and Python/platform conditions are preserved; repeating generation produces identical bytes.

Validation on Windows/Python 3.12: fresh hash-checked release-tool installation, standard python -m build, and python -m twine check all passed. The wheel and source distribution each installed into a separate fresh environment and passed scripts/verify_python_distribution.py for version 0.5.0, installed imports, bundled catalog schemas and Config construction. Both passed cmcp --help.

The original lock has the same Git blob as cA2A #172's original release lock, whose Windows hash-checked resolution failed on missing colorama. Hosted CI 35129065131 passed all six Windows/Linux Python 3.11-3.13 jobs and governance. CodeQL 35129065102 passed on 2434330. Release packaging was checked locally; no publication was performed.

[imran-siddique]

Reviewed the repaired dependency diff at 2434330. The build bump uses the regenerated universal release lock. Recorded hash-checked installs, wheel/source-distribution metadata and CLI smoke checks pass.

The validation evidence is in the PR description. This supplies the maintainer review; the repository still requires an independent reviewer to approve the latest push.
