Subagents: one slider with two handles, Min and Max; 1 is the agent alone

The chip's popover is one range from 1 to the server's cap (subagents.cap, /models
subagents_cap, else 32) with two handles: two range inputs overlaid on one track, the span
filled, aria-labels Min and Max with value text, keyboard as any slider, Min never past Max,
the values said above it ("Min 1 · Max 4") and the two ends under it. "Fewest"/"Most" are
gone. The hint says what the numbers count: the chat's own agent -- 1 is the agent alone, Max 4
is the agent and up to 3 subagents. Untouched on a new chat it still leaves the server's
defaults (1-4, shown). i18n: Min, Max and the new hint in all eight languages. CHANGELOG.
