VNX-GH-218: Signed commits not required

The default branch accepts unsigned commits.

Updated 02 Nov 2026Checked against cli@24498404a, vdb-sca-match@v0.8.14

Commit author fields are free text. Without signature verification a commit can claim any author, which undermines audit trails and author-based automation.
