* fix(tui): keep every word of an unquoted --print/--json message
--print and --json took a single optional value and never read the
positional words, so `deerflow --print summarize this repo` sent only
"summarize", `deerflow summarize this repo --print` exited 2 asking for a
message on a terminal, and with piped stdin the typed words were ignored.
Both flags now take every following word and fall back to words given
before them, as --cli does; a typed message wins over piped stdin. A
message split around the flag is refused with exit 2, because argparse
loses the word order between the two parts.
* docs(changelog): reference #6636
* fix(tui): refuse --print and --json together
Only one headless mode runs, so the other flag's words were dropped:
'--print hello --json world' ran with 'hello', and '--print --json hello'
asked for a message. Put both flags in a mutually exclusive group so argparse
exits 2 for every combination.
