Release 0.137

v0.137.0 — 2026-07-16

Tables v2.2: export formats + linked reference columns. Export any table straight from the grid via a format dropdown — Excel (.xlsx), Markdown, or CSV (a multi-tab workbook exports every tab). Linked reference columns (type: 'reference', from v2.1) gain a first-class grid affordance: a 🔗 menu on a linked column header to Change source… or Delete link (unlink keeps the cell values as plain text). A reference is a convenience picker — the chosen value is copied as plain text, Excel data-validation style, so table_sql sees an ordinary column; soft integrity flags values missing from the source as DANGLING REFS in the profile, and removing a source degrades the column to plain text with values intact.

A reference column always stores as text — the engine maps reference → select at every storage / read / filter boundary via storageType(). (An earlier cut of v2.2 explored per-column reference modes — a checkbox variant and a deferred multi — but they were removed before release: the checkbox mode was flaky and the mode machinery widened the type surface for no user-visible gain. A linked column now has exactly one behavior.)

Deploy: tag-only bump — no migration, no compose change.
