datatable — data-value-aware sort

The one host-side change SPEC-103 takes for typing: extend the datatable sort comparator to prefer a cell's data-value over its textContent, mirroring what chart already does (cell.dataset.value ?? textContent). This is what lets data's numeric typing produce correct sorts of human-formatted numbers (currency, thousands separators, units) — and it equally fixes hand-authored tables, so it is a general improvement, not a data-specific hack.

Scope

  • Sort comparator — in packages/behaviors/src/behaviors/datatable.ts, read each sortable cell's value as data-value ?? textContent when building the row model (the comparator currently uses localeCompare(…, { numeric: true }) on text only). When data-value is present and numeric, sort numerically; otherwise fall back to the existing natural-string collation.
  • No markup churn — purely additive; tables without data-value sort exactly as today.
  • Tests — a table with data-value on a currency-formatted column sorts by the numeric value, not the formatted text; a plain table's sort is unchanged.

Acceptance Criteria

  • The datatable sort comparator prefers data-value over textContent, sorting numerically when the value is numeric.
  • Tables without data-value sort identically to current behaviour (regression test).
  • A data-generated table with typed columns (currency / thousands separators) sorts correctly.

Dependencies

  • None — independent of the data rune (it also benefits hand-authored tables). Pairs with the SPEC-103 data work to complete the typing story, but blocks nothing.
