Add visual highlighting for slash commands as you type in the chat input. Commands are highlighted with the same blue tint used in sent messages.
- Move typography (font-size, font-family) to wrapper container - Overlay inherits all styles via 'font: inherit', no duplication - Make textarea text transparent when command prefix exists - Overlay positioned behind textarea, shows through transparent text - Caret remains visible via caret-color - Background moved to wrapper so overlay renders correctly - CommandPrefixText accepts className for font override when needed

Summary
Add real-time visual highlighting for slash commands as you type in the chat input, using the same blue tint (
--color-plan-mode-light) that appears on commands in sent messages.Background
Currently, slash commands are styled with a blue highlight color only after sending the message (via
CommandPrefixBadgeinUserMessageContent). This PR brings the same visual treatment to the input field itself, providing immediate feedback that a command is being typed.Implementation
CommandHighlightOverlaycomponent: Extracts the command prefix (first line starting with/) and renders it with the highlight color. The rest of the text is transparent so the original textarea text shows through.VimTextArea: The overlay is positioned absolutely on top of the textarea withpointer-events: noneso all interactions pass through to the underlying input.extractCommandPrefixfunction covering various input patterns.How it works
