relink-media

I'd like you to add a skill to Wideframe called "relink-media".

What it should do:
Repair offline media in a project after files moved, repointing every reference to the real file.

Before you run anything, ask me to confirm:
- What changed (drive renamed, folder moved, files renamed)?
- The old root path and the new root path?
- Which project file(s) are in scope?
- Work on a copy of the project (recommended)?

Then do the work:
1. Run prproj-validate and prproj-inspect to list every offline or dangling reference.
2. Search the new locations for matching files by name and size.
3. Repoint each reference to the found file with prproj-edit, working on a copy.
4. Re-run prproj-validate to confirm.
5. List any reference still unresolved.

Do not grade your own work. When the output is ready, hand it to a separate verification subagent that has its own context window. Give it the output, the choices I confirmed, and the pass criteria below. It reviews the quality, writes specific feedback, and returns PASS or FAIL.

Pass criteria:
- prproj-validate reports zero offline or dangling references.
- Each relinked file matches the original by name and size.
- Any file that could not be found is listed explicitly.
- The original project is preserved.

If it returns FAIL, apply the feedback, redo the affected work, and verify again with a new subagent. Repeat until it returns PASS, then show me the result.

Once it works, save it as a reusable skill named "relink-media" so I can run it again by saying /relink-media.
