Subagents: Min and Max, one range with two handles, counting this agent (harness spec 3.3.0)

/effort's Subagents row and /team size are a two-handle range from 1 to the cap (left/right move
the handle in focus, tab the other, enter sets both); the dialog gains a range row. Every text says
Min and Max, never fewest/most, and that the count includes this agent: "Subagents: Min 1, Max 4 -
1 is this agent alone". /settings shows the same beside agents.min / agents.max; config schema
and the bounds refusal likewise. CHANGELOG in the 2.0.0-beta.5 section.
