Problem

Homeboy issue Extra-Chill/homeboy#7898 needs an apply-capable managed-worktree provider. Data Machine Code already owns safe target resolution and workspace patch apply, but it does not expose an adapter that consumes homeboy/agent-task-promotion-apply-request/v1 on stdin and emits homeboy/agent-task-promotion-apply-response/v1 on stdout.

The active Homeboy DMC provider therefore has resolve, list, cleanup_preview, and cleanup_apply, but no commands.apply. The generic Homeboy contract half is in Extra-Chill/homeboy#9719 plus the stacked #7898 candidate.

Expected

• Add a DMC-owned CLI/ability adapter that reads the typed Homeboy promotion request from stdin.
• Resolve the requested <repo>@<slug> through DMC registry/safety policy.
• Reject primary, dirty, mismatched, or untrusted-unpushed destinations before mutation.
• Apply patch_path through the existing workspace patch primitive rather than duplicating git mutation logic.
• Emit homeboy/agent-task-promotion-apply-response/v1 with the canonical managed worktree path and bounded command evidence.
• Provide a discoverable invocation suitable for Homeboy worktree_providers.dmc.commands.apply, including {handle} argv substitution.
• Add an end-to-end CLI test covering valid apply plus dirty/unpushed/path mismatch rejection.

Integration proof

After the Homeboy and DMC changes are available, run a normal homeboy agent-task cook --to-worktree <dmc-handle> without per-run --provider-command/--provider-argv; promotion must resolve DMC configuration, apply a non-empty patch, run deterministic gates, and preserve the canonical workspace path/evidence.
