refactor: simplify subagent session reuse
Review pass over the reuse change. No intended behavior changes.

- share one definition of the initial generation from fabro-types instead
  of three copies across fabro-types, fabro-agent, and the supervisor
- give each child one SubAgentHandle instead of threading the supervisor's
  state, callback, and notification sender through five functions, and
  collapse the repeated signal-then-drain pairs into publish()
- move `reusable` inside SubAgentStatus::Finished so a closed agent can no
  longer be marked reusable
- clear the lifecycle draining flag with an RAII guard, so one panicking
  callback cannot silence every later lifecycle event
- tear down a session that failed to initialize right away rather than
  holding it and its sandbox until the parent closes the agent
- look agents up through SupervisorState::agent/agent_mut instead of five
  copies of the same not-found error
- drop the unreachable cleanup_started branch and the test-only emit_event
  whose only caller was its own test
- render subagent starts from one ProgressEvent and one display method,
  deriving the spawn/turn distinction from the generation
- set projected subagent status through one helper instead of four
  identical reducer arms
- drive the generation-pinned wait test through spawn/send_input rather
  than hand-writing private supervisor state
