Server behavior and tool contracts may change. Tool availability depends on the server configuration.

Set the window default for synchronized pane input. Individual pane overrides still determine the effective configured cohort, so enabling this can amplify what one [send_keys](https://libtmux.org/en/rs/latest/mcp/tools/send_keys/) call reaches. Change tmux state; no client-supplied executable input.
