SheetMog

A focused patch release polishing in-cell formula editing and fixing a column/row resize failure on sparse sheets.

Primary PR: #13 — Release v0.8.1

Formula editing

• Visible formula caret — the in-cell editing caret was occluded by the syntax-highlight overlay, making cells look uneditable; the caret now renders above the highlighter and stays visible while typing.
• Correct formula font — formula text in the in-cell editor rendered at the inherited browser default (oversized and misaligned with the caret); it now uses the cell's resolved, zoom-scaled font so text and caret stay in sync.
• Clicking inside the edited cell no longer commits — a click inside the cell being edited silently committed/erased the formula instead of moving the caret; clicks within the editor now place the caret normally, while clicks on other cells still commit-and-move and insert references.
• Formula argument hint no longer covers the formula bar — when editing in the formula bar, the argument hint is now anchored below the bar (instead of overlapping it) and collapses to a single-line signature that sits within the column-header height, revealing full argument/function descriptions on hover.

Compute

• Column/row resize on sparse sheets — resizing a column or row whose index lay past a sheet's materialized axis extent failed with a misleading SheetNotFound; the resize path now auto-grows the axis (matching the cell-write path) so resizes succeed and persist across reload.
