Use fzf to pick the agent in agent-cmd.sh

Browse Source 
Move agent discovery out of `agent.sh` so the picker runs on every new
pane, including manual splits. Set the agent session's default-command
to agent-cmd.sh and re-apply session options on every invocation so
changes propagate to live sessions.
