Summary

 Compatibility Tool status
- show the first supported CrossOver copy
+ show each supported Rosetta and FEX copy
+ offer an Active build picker when both runners are set up

Setup now verifies and patches a cloned build before moving runners/current. Switching checks the selected clone and license, stages its ntdll patch, and restores the previous bridge files if activation fails.

Evidence

• Before: The app showed one CrossOver copy and had no way to select between installed runners; setup moved current before patching completed.
  After: The rebuilt app set up Preview 20260821 Rosetta, then the picker switched Rosetta → FEX → Rosetta → FEX. The Status screen and runners/current agreed at every step. FEX was left active.
• Tests: 353 Swift tests and the repository's native checks pass. make app produced a signed bundle that passed codesign --verify --strict.
• Limit: This checks runner setup and selection, not a game launch under Rosetta. The test left a Rosetta runner clone alongside the existing FEX clone; it did not change Steam or game prefixes.

Merge Danger

Door: Two-way

Blast Radius: Compatibility tool setup and active-runner selection. Existing runner clones and the current link remain on disk when the app is rolled back.

@NotProtonNot You're welcome, when you push the roadmap let me know and i'll work on something off of it :)

p.s. setting up a review bot like coderabbit may be helpful for the repo, just a suggestion as I tried it the other day and it's really nice
