Match Row: selects all rows where the cell in the current column
equals the current cell's value. Selection spans first-to-last
matching row across all columns.
Delete Row (Cmd+Backspace): deletes every row in the current
selection, or the single current row if nothing is selected.
Ensures at least one empty row always remains.

Opens a modal with a text field supporting autocomplete of column
names. Enter comma-separated column names in priority order;
rows are sorted ascending using locale-aware numeric comparison,
first by the first column, then by the second, and so on.
Autocomplete filters to matching headers, excludes already-chosen
columns, and supports keyboard navigation (arrows + enter).

- Cap cell and header max-width to 150px (was 200px for best-fit)
- Bump header z-index to 10 (row-number corner to 11) so sticky
headers stay above data cells when scrolling horizontally
- Remove position:relative and z-index from cursor-cell so it no
longer creates a stacking context that overlaps sticky headers
- Sort command palette entries alphabetically (case-insensitive)
