feat: add bb_lifecycle optional async observer dispatch (#913)

- bb_lifecycle_observe_async() decouples an observer callback from the
  emitter task via a shared bqueue + drain task, opt-in behind
  CONFIG_BB_LIFECYCLE_ASYNC (default n); sync bb_lifecycle_observe() is
  unchanged and remains the default
- async substrate lives entirely in a new bb_lifecycle_async.c TU, fully
  #if-gated so bb_bqueue/bb_task refs drop out cleanly when off
- lazy-created singleton queue/task, non-blocking enqueue with a
  rate-limited drop-log and bb_bqueue_dropped() counter
- host test seam: bb_lifecycle_async_drain_dispatch_for_test() and
  bb_lifecycle_async_test_drain_once() exercise the same dispatch path the
  production drain task runs, without needing a real thread
- host build runs the async path under BB_LIFECYCLE_ASYNC=1; default
  (production) build stays gated off, proven by the unmodified smoke suite
- adds an esp32-lifecycle-async smoke variant compiling the async path
  (bb_task_create STATIC + bb_bqueue) for a real espidf target
