The TUI ships with no keybind for session.toggle.generic_tool_output
(the keymap in packages/tui/src/config/keybind.ts sets it to
keybind("none")), so users see collapsed tool cards and no output
at all unless they either open the command palette or rebind the key.
Adds a 'ctrl+t' binding to ~/.config/opencode/tui.json so toggling is
one keystroke away, and documents the palette path + the rebind path
in the README so the user has both. No plugin code change.
