refactor: unify task-health registry on bb_task, break bb_timer cycle (#723)

- bb_task_registry gains a periodic base-scan job (pure evaluator in
  components/bb_task_registry/bb_task_registry_base_scan_common.c, thin
  espidf shell doing uxTaskGetSystemState) that upserts/touches bb_task's
  base registry for every live task and sweeps entries that have gone;
  cadence via new CONFIG_BB_TASK_REGISTRY_BASE_POLL_MS
- bb_task gains bb_task_base_touch(handle, now_tick) so the scan can mark a
  handle seen without clobbering its budget/wdt_arm
- bb_task_registry_register()/deregister() now join/unjoin bb_task's base
  registry by handle, linking the overlay's authoritative budget/wdt state;
  the lock-free bb_task_registry_feed() hot path is untouched
- bb_health_stack becomes a pure observer: deletes its own mark/sweep table
  and bb_timer poll, registers a low-stack handler via the new
  bb_task_registry_set_low_stack_handler(); CONFIG_BB_HEALTH_STACK_MAX_TASKS
  retired (shares CONFIG_BB_TASK_BASE_MAX), CONFIG_BB_HEALTH_STACK_LOW_BYTES
  and _AUTOSTART kept
- bb_timer's two task-creation sites (bb_timer_disp, worker) migrate to
  bb_task_create(); bb_timer_disp self-subscribes/self-feeds the hardware
  WDT instead of a parent-side bb_task_registry_register call; drops
  PRIV_REQUIRES bb_task_registry, adds bb_task + bb_wdt -- breaks the
  bb_timer <-> bb_task_registry dependency cycle
- /api/diag/tasks is untouched: its bb_task_registry_count/capacity/dropped/
  lookup_budget/lookup_sw_wdt calls keep their existing signatures
