Fuzzy-searchable picker for slash commands.
Opened by typing `/` in the prompt. Wraps the [`Combobox`](tui::Combobox) widget from the `tui` crate, populated with [`CommandEntry`] items that include both built-in commands (`/clear`, `/settings`, `/resume`) and agent-provided commands.
# Rendering
Each entry shows `/<name>` left-aligned with the description to the right. The selected row is highlighted. An optional `[hint]` suffix appears for commands that accept arguments.
