In the interactive CLI, the aggregator's tool calls under a MoA preset (or
any non-streaming model call, e.g. copilot-acp) appeared to overwrite each
other instead of building scrollable history. Each tool only updated the
transient spinner line; no committed scrollback line was printed.
Root cause: persistent tool lines in _on_tool_progress's tool.completed
branch were gated on tool_progress_mode in {all, new}, omitting 'verbose'.
Streaming models hid the bug because _on_tool_gen_start commits a 'preparing'
line per tool during streaming; non-streaming calls (MoA forces
_use_streaming=False) never emit that, so under 'verbose' there was no
committed line at all — only the self-overwriting spinner.
'verbose' is strictly more than 'all', so it now commits the same scrollback
line. Verified live via interactive PTY on the MoA opus-gpt preset: three
terminal calls in turn 1 and two in turn 2 each render as separate persistent
lines.
