feat(#19): wire skill scanner into /clawforge-submit with auto-blocking

The /clawforge-submit command now enforces security scan results before
upload. If the scanner detects critical findings (shell execution, dynamic
code eval, env harvesting, crypto mining), the submission is blocked and
the skill is NOT uploaded to the control plane.

Non-critical warnings are still allowed through with a note that the admin
will see them during review. The scan runs automatically as part of the
bundleSkillForSubmission step, so no separate scan command is needed.

Includes 6 tests verifying scan summary formatting and blocking logic.
