chore(copilot): delete the mention machinery nothing calls

The workflow panel's copilot tab renders `MothershipChat`, and that component
brings its own input — so `panel/components/copilot` no longer holds a
component at all, only the hook library the old input used. Five of those hooks
have no caller anywhere: `useMentionData`, `useMentionKeyboard`,
`useCaretViewport`, `useMentionInsertHandlers`, `useTextareaAutoResize`.

They are not all of it. `home/components/user-input` still imports
`useFileAttachments`, `useMentionMenu`, `useMentionTokens`,
`useContextManagement`, and `useIntegrationAutoMention` from this directory,
so it survives as a shared hook library rather than dead weight — which is why
this removes the uncalled five rather than the folder.

What they alone reached goes with them: `getFolderData` / `getFolderLoading` /
`getFolderEnsureLoaded` and the `FOLDER_CONFIGS` table describing every mention
folder, `buildMentionHighlightNodes`, the `MentionFolderNav` type, and the
slash-command tables. Of the 266-line constants file only `SCROLL_TOLERANCE`
had a live reader left.
