Commit Message

feat(rust,wasm): facet pricing-wave trace hook (setFacetTrace/facetTrace)

Adds an opt-in recorder for the facet-pricing waves so a slow facetCounts
can be localized. count_categories_batched records one A/B/C WaveStat per
contributing split (coalesced reads + bytes per wave); setFacetTrace(true)
enables it, take_facet_trace()/facetTrace() drains it. Zero-cost when off.

The trace makes the wave structure legible: pricing is two dependent round
trips (A = head + tail-header prefixes, then C = needed tail containers; B a
rare re-read), all splits concurrent -- not a per-category serial chain.
Wave A dominates, issuing ~one scattered tail-header read per priced
category per split, so its read count scales with topPerField x fields x
contributing splits and is bounded by the fetch window, not reduced by it.

Also: coalesced_span_count helper (fetch), probe prints the wave rollup.
