Headline: two big UX shifts in the composer.
The @-mention picker is rebuilt as a streaming file browser — @ alone shows the immediate directory listing, anything you type fires a cancelable walk that streams matches in as it finds them. Fixes the unusable-on-large-repos behavior reported by @xlingyun8-maker (5000 files would evict 90% before ranking, picker showed nothing).
The mouse wheel now scrolls chat history regardless of where the cursor is, via SGR mouse tracking — wheel events route through mouseScrollUp/Down instead of being mistranslated as ↑/↓ by Windows Terminal / ConPTY.
Plus: structured TipCard variant (cleaner edit-gate hint), real /keys command with full keyboard + mouse + copy-paste reference, and a one-time mouse/clipboard tip on first launch so users don't think the prompt is broken when right-click stops doing the terminal's native paste.
Critical fix: dashboard was silently overwriting CLI-side /language changes by pushing localStorage back to the server on every page load.
