BuildForTaskAsync's fresh-session path flattened the task title+description
into one positional CLI argument, which the ConPTY host joins into a single
command line and claude re-splits on whitespace -- any dash-leading token in
the description (e.g. "->", "--abort") was misread as an unknown option, and
a raw multi-line prompt truncated at its first newline regardless. Now the
brief is written to ~/.todo-app/task-sessions/<taskId>/brief.md and exposed
via --add-dir, with a single-line kickoff pointing claude at it -- the same
pattern BuildForMergeHelperAsync and the planning launcher already use.
