Harness spec 3.3.0: the Subagents setting is Min and Max, one range with two handles, counting the agent itself

loop.json subagents.setting: min/max are "Min" and "Max" (not fewest/most), with a hint and a short
form saying the numbers include the session's own agent - 1 is the agent alone, Max 4 the agent and
up to three subagents. team.md §2 and subagents.md §4 state that, and the UI rule: one range from 1
to the cap with two handles (a slider; two numbers on one line in a terminal). team_add says the
size includes the caller. Conformance team: max 2 is the lead and one task subagent.

Still 3.3.0, unreleased: edited in place.
