-**Run.** Every item opens a full-width split along the bottom of the window (`split-window -v -f -l 25%`), 25% of its height, in the task's directory. The command is passed to `split-window` as separate arguments, so no shell reparses it. `--run` calls `pj --run`, which keeps pj's `openlogs` wrapping of `dev`/`start`/`serve`/`watch` tasks, and `--cmd` runs a quick action. Either way, when the command exits the script prints `[exit N]` and `exec`s `$SHELL`, so the pane keeps the output instead of closing.

While the command runs, <kbd>ctrl-c</kbd> stops only the command (the script traps `SIGINT`), so the output stays. Once the command exits, the script prints `[exit N] enter or ctrl-c to close`, and <kbd>enter</kbd> or <kbd>ctrl-c</kbd> closes the pane; other keys are ignored.
