Harness spec 3.2.0: teams — subagents that work together

team.md: a lead adds members (team_add) that work in the background on
the parts they own; members may lead areas of their own. The chat
setting agents {min, max} (defaults 1/4, an instance cap of 32) bounds
the whole tree, task helpers included; a team is offered only where
subagents are enabled and the model serves two requests at once
(capacity.parallel). A manager's work calls — risk write or execute,
bar job_stop and reading bash — answer a fixed refusal while the tool
list stays unchanged. The room: team_send to names or all, delivered
under "[Team message from X to Y:]" at the next step or waking a
finished member; a member's final reply is its report to its manager;
team_read shows the tree and the visible part of the room; team_stop
stops a subtree. Past the model's capacity a member waits for a slot,
the lead first. Size notes in context.note; texts in loop.json team;
prompts blocks/team_lead.md and team_member.md; tools allowed by
default. Conformance area team, written from a reference model.

The CLI embeds the new tool and prompt files; its tools are pending.
