Keep subagent boards pinned while background workflows run

A background subagents.lua workflow outlives the tool call that started
it, so settling the outer result unpinned a board whose agents were still
working. Track a per-tool-call workflow count and derive the pin from
both the tool being active and that count, so the board only returns to
transcript order once its last workflow finishes.

Also show the reasoning level alongside the model on agent cards.
