Fix/ctrlregen supply chain hardening - #25

--model now accepts an @revision suffix passed through to diffusers from_pretrained, keeping Hub loads reproducible and shrinking the malicious-repository swap surface behind CVE-2026-44513/CVE-2026-45804 (diffusers trust_remote_code bypass family). Malformed values exit 2. Default behavior is unchanged when no revision is given.
Weekly scoped pip-audit over skills/remove-ai-marks/scripts/ requirements-*.txt. The Dependabot alerts for these research pins are dismissed as tolerable risk, so this job keeps the findings visible without blocking CI.

In @.github/workflows/pip-audit-optional.yml:
- Line 30: Update the actions/checkout step in the pip-audit workflow to set
persist-credentials to false, preventing the GitHub token from being stored in
local Git configuration before third-party Python steps run.
- Around line 35-36: Update the “Install pip-audit” workflow step to install the
reviewed version pip-audit==2.10.1, while retaining the pip upgrade and existing
installation flow.
- Line 28: Move continue-on-error: true from the job-level configuration to the
audit step so setup failures remain fatal while audit findings stay
non-blocking. In the audit step’s script, add exit "$rc" after the final echo to
preserve and return the audit status.
In `@skills/remove-ai-marks/scripts/markdiffusion_harness.py`:
- Around line 125-135: Update _split_model_revision to accept only revisions
that are exactly 40-character commit IDs, rejecting branch names, tags,
malformed, or missing revisions; ensure the default model is pinned or
explicitly rejected, and add tests covering branch, tag, and absent revisions.
Pin the diffusers dependency in requirements-markdiffusion.txt to an immutable
version.
