* fix: coalesce equal histogram quantile bucket boundaries
Merge numerically equivalent bucket boundaries before monotonicity repair, preserving the allocation-free path for unique boundaries. Share coalescing with histogram_fraction and cover duplicate boundaries with unit and SQL regressions.
Fixes#9443

* fix: keep duplicate infinity buckets in one histogram group
Confirm classic histogram completion at a series/timestamp boundary or EOF instead of the first positive infinity. Retain lookahead across batches and reject incomplete optimistic groups so equivalent infinity labels reach numeric coalescing together.
Add stream and SQL regressions for duplicate infinity labels, including established bucket counts and EOF. Correct older fixtures to use distinct keys for distinct histogram groups.

* fix: avoid buffering histogram groups with invalid trailing bounds
Discover candidate bucket counts at the first group boundary and let optimistic validation fall back to safe mode for malformed bounds. Document discovery and cover trailing invalid and null labels with a focused streaming regression.
