patch

A multi-line prompt sent through the mux (POST /api/sessions/:id/input with useMux) now keeps its line breaks. sendInput used to strip every \n before the text reached tmux, so "line one\nline two\r" arrived as line oneline two. The lines now go in as one bracketed paste, the same paste a single-line prompt already uses, and the Enter after it submits them together; multi-line text without an Enter is pasted too instead of typed. A shell runs each line. The submit check that re-presses a stranded Enter does not yet recognise a multi-line paste in the composer, so the unattended senders stay single-line: cron still rejects multi-line prompts, respawn's update and kickstart prompts and the auto-compact focus prompt now have their lines joined with a space (they used to run together), codeman agent send and the TUI keep refusing or joining multi-line input, and the agent skill's sendwait now joins the lines of a multi-line prompt with a space too.
