+Add an About dialog in the TUI accessible from the command palette (under "Kilo") or via the `/about` slash command. Shows version, channel, runtime/platform, config path, project root, connected providers, and default model, with helpful links (docs, GitHub, issues, Discord) and a `c` shortcut to copy diagnostics to the clipboard.
