What does this PR do?

Fixes a TypeScript compilation error (TS2411) in the desktop app build. The SlashItemMetadata interface extends Record<string, string>, which requires all property values to be string. However, rawText was declared as optional (string | undefined), causing tsc -b to fail during npm run pack on Windows. Since rawText is always assigned in toItem(), making it required resolves the type incompatibility without changing runtime behavior.

This error appears with TypeScript 6.0.3 and strict: true in apps/desktop/tsconfig.json.

This PR addresses the TypeScript compilation error described in #39404. The separate updater reliability issue (deletion of existing app on failed update) is not covered here.
