🩺 Stability & Availability | 🟠 Major | ⚡ Quick win
Handle listing failures and stale responses in init.
init sets searchStatus to loading and awaits clientContent.list. If that request rejects, the status stays loading, the promise rejection is unhandled, and the search palette keeps a loading state with no recovery. The watcher on line 48 can also start a second init before the first resolves. The later assignment then wins by arrival order, so files can hold results for the previous collection.

Make the metadata access in editLink consistent.
Line 119 defaults meta.extension. Lines 120 and 121 then read meta.stem and meta.source without a guard. If either field is absent for any content source, this computed throws during render and breaks the whole page, not just the edit link. Either guard all three fields, or drop the extension fallback because the contract guarantees the fields.

🩺 Stability & Availability | 🟠 Major | ⚡ Quick win
Add a timeout and a status check to the schema fetch.
loadNuxt3Schema calls an external host during Markdown transformation. The call has no timeout, so a slow unpkg response blocks documentation rendering for the whole request. The code also ignores the HTTP status. If unpkg answers with a non-ok JSON error body, that body is memoized in schemaPromise and every later request reuses it, because the catch in injectGeneratedConfigDocs never runs.
