The SSH tool renderer fed the raw command into renderStatusLine's
description, so any newline in the remote command expanded the
single-line tool header — the bordered output block then opened
mid-command and the rest of the SSH cell rendered against a broken
frame.
The renderer now keeps only [host] in the header and renders the
full command (with a dim $ prefix and tab sanitization) as its own
framed section above Output, matching the bash renderer's shape.
renderStatusLine also flattens CR/LF in title, description, meta,
and badge labels so no future caller can accidentally produce a
multiline tool header.
Covered by:
- test/tools/ssh-render.test.ts: multiline command stays out of
the header and every command line is present in the body, for
both renderCall and renderResult.
- test/tui/status-line-newline-guard.test.ts: embedded LF, CRLF,
and lone CR in description/meta are flattened to spaces.
