Teams in the CLI (harness spec 3.2.0, team.md)

The four team tools (tool/team_tools.ts) on the rules of team/team.ts,
driven from real turns by team/runtime.ts:

- Members run on the subagent job machinery (app.ts spawn with `member`):
  background, unattended, their own prompt from blocks/team_member.md
  (the whole of team_lead.md for one with lead: true), team_send and
  team_read (team_add and team_stop for one that leads). Not jobs to the
  model: job_list and the job_* tools skip them; a client over the link
  still sees them as subagent jobs named "<name>: <role>".
- The room: messages and reports with their marks, delivered at the next
  step boundary or waking a finished member or the idle lead; report
  posts to the manager.
- A manager's work calls answer the refusal before the permission check,
  by risk class (an MCP tool by its readOnlyHint); the tool list is
  unchanged. job_stop and reading bash stay.
- Slots: the lead waits for one before its turn (Esc stops the wait);
  members wait in order; task helpers in a team count toward the size
  and hold a slot; job_send restarting a helper is refused when full.
- The offer is decided with the prompt and kept with it: a resumed
  session takes it from its kept tool list.
- The size: agents.min/max settings, refused outside 1 <= min <= max <=
  cap, kept across /new and resume; said in a note on the first message,
  after a change, after a compaction and a rewind.
- TUI: /team (tree and room, size, stop a member, dialogs for both), an
  "agents" row beside the effort in /effort, "team n/max" in the status
  bar. /team works over ACP too.

tests/team.test.ts runs a lead, a member and its report through the app.
