[core] fast_select stats: spin-poll to bucket load-bearing hits by µs

Replaces the single load_bearing counter with three buckets measured
via a bounded (100µs) spin-poll of the task notification value after
the scan finds data:

  race  (<10µs)  — notification arrived within ~10µs: callback-ordering
                   race between rcvevent write and xTaskNotifyGive a few
                   instructions later. Scan is noise.
  micro (<100µs) — notification arrived within 100µs: still noise at
                   loop_interval scale.
  stall (>=100µs) — notification did not arrive within the poll window.
                    Only this case could represent a real latency spike
                    that the scan is rescuing.

The 100µs spin cap is intentional: if we are wrong and this IS a real
stall, we only add 100µs to that one unlucky loop iteration.

The immediate ESP_LOGW on each hit now includes gap_us and the bucket
label so individual events can be investigated.
