fix(ci): dependabot commit-message prefix → chore (commitlint compat) (#6)

Default dependabot commit subjects use ecosystem prefix (e.g. nuget:, pip:) which is rejected by @commitlint/config-conventional. Adding commit-message.prefix:chore so commits become chore(scope):... and pass commitlint.

Surfaced by /jc-coding-fleet-driver --mode=all (2026-04-28) Phase D.
