Dockerfile preparation now fetches only the required base and source commits through the repository cache helper, instead of cloning all branches and fetching every pull-request ref for each task. Each task has a separate checkout and the lock covers cache mutation and checkout preparation only. Removes four uncalled wrappers, their string-only guard and the unused Python runtime.

Validation: real Git fixtures prove pull-only commits, one cold fetch, no extra warm fetch, divergent merge-base coverage, missing revision rejection and VERSION enforcement. Image contracts and lints passed. Agent consumers will use the new v8 image after publication.
