oleh	af9ee1e4c0	Add aggregation, binning, granularity, sort, and stacking to the Chart Builder ... - Per-channel transforms: aggregate (sum/mean/median/min/max), quantitative bin, and temporal timeUnit granularity; bin and aggregate are mutually exclusive. A field-less "Count of records" measure (Voyager's count(*)). - Chart-level sort (rank a categorical axis by its measure) and stacking (zero / 100% normalize), each shown only when it applies. - Field type is a fixed N|O|Q|T segmented control with the column's invalid types disabled; SegmentedControl gains APG-correct disabled options. - A crowded-category-axis warning (a raw measure drawing one mark per row over a large dataset) and a disabled-Create hint (says why it's disabled). - Drop the Create success toast — the new snippet is immediately visible. - Docs: spec §06, research-doc §8 backlog (incl. the cardinality/extent profiling TODO), architecture 01 (stable-selector rule) and 05 (builder-local preview), and a profiling breadcrumb.	2026-06-06 18:04:24 +03:00
