/dh:interop — Superpowers Plan Interop Adapter

Routes a Superpowers plan file through the /work-backlog-item pipeline to produce a SAM task plan, then writes back-references into the original plan. Does not re-implement any pipeline logic — delegates entirely to /work-backlog-item.

The plan file path is provided as $ARGUMENTS.

Invocation: /dh:interop <path-to-plan-file>

---

Step 1 — Validate the argument

If $ARGUMENTS is empty, abort immediately:

ERROR: `/dh:interop` requires a path to a Superpowers plan file.
Usage: `/dh:interop docs/superpowers/plans/YYYY-MM-DD-slug.md`

Use the Read tool to open the file at the path given in $ARGUMENTS. If the file does not exist or cannot be read, abort:

ERROR: Cannot read plan file: {path}

Make no changes to the file or backlog before this check passes.

---

Step 2 — Extract fields from the plan file

Extract the following fields by exact pattern match against the raw file text. No inference.
