Chat extensions

ChatSidebar

ChatGPT-style conversation list with search, pinned and recent sections, kebab menus, and keyboard navigation. Self-contained — no popover libs.

Sourcesrc/components/ai/chat-sidebar.tsx

New-chat button, search, pin/archive/delete handlers, and an archived toggle at the bottom.

Omit the action handlers for a pure navigation sidebar — no menus, no delete shortcut.
