…ans (auto-analyze core)
Pure, tested tokenizer for the 'auto-analyze a line' flow: split on whitespace at
bracket/quote depth 0, keeping [..]/(..)/{..}/<..>/quotes whole, each token → a
column (col1..). Feeds the tested compilePaint (which types each token). +3 tests.
Renderer button (🔍 Auto-detect columns) wiring lands next. tsc 0 · 631 tests.

…o the panel The 'auto-analyze a line' flow (replaces the hidden Refine-from-data as the star): click '🔍 Auto-detect columns' in the Column Layouts builder → it tokenises the sample line (mirror of the tested autoDetectSpans: whitespace split, brackets/quotes kept whole) into paint spans → the tested compilePaint TYPES each (date/int/word…, borders literal) → the draft columns land in the panel to rename/tweak, then Use as columns. The data-driven wrapper generalisation still folds in via the preview, but now it's part of an EXPLICIT analyze action, not hidden. tsc 0 · 631 tests · bundle.

Explicit 'auto-analyze a line' for the Column Layouts builder: click 🔍 Auto-detect columns → tokenise the sample line (pure tested autoDetectSpans: whitespace split, [brackets]/quotes kept whole) into paint spans → the tested compilePaint TYPES each (date/int/word…, borders literal) → draft columns land in the panel to rename/tweak. Replaces the hidden Refine-from-data as the star flow (wrapper generalisation folds into the explicit analyze). +3 tests. tsc 0 · 631 tests · bundle.
