Connector search: File Search entries crowd out the app the query names #1457

Seen in Cloud catalog_search events on 2026-11-02:

• A word about documents next to an app name hands the first places to File Search: `lexware dokumente` shows SFTP and WebDAV before Lexware Office; `telegram send document` and `excel files` get the File Search hint too, though those documents live in the app.
• A query about another app meets File Search entries through their aliases and ranks them among the apps: `amazon` lists S3 (File Search) right after the Amazon connectors, `hero` (HERO Handwerkersoftware) puts QNAP first via its alias "QuTS hero".
• `excel`, `word` and `outlook` list every File Search entry, because their descriptions say "PDF, Excel, Word and Outlook files". In the chat (5 results) that leaves one real result and four File Search entries.

Expected: a File Search suggestion for storage systems and for document-only queries; an app named in the query comes first; File Search entries met only through an alias rank after the apps the query names, and entries met only in their description are left out of queries about other apps.
