Table selection context + navigation helpers.

`getTableContext` walks the selection up from `$from` and reports which table / row / cell the cursor is in, plus the table's row/column counts, whether a multi-cell selection is active, and the current cell's border + fill colors (so the toolbar's color pickers can show the live values).

`goToNextCell` / `goToPrevCell` are tab-stop-style cell navigation commands registered by the plugin extension.

interface TableContextInfo

Cell-border commands. Each command applies a preset / individual side / color / width to the cells targeted by the current selection (single cursor cell or active `CellSelection`).

All four commands use the shared `buildTableGrid` lookup to find each cell's neighbours in the grid, then sync the matching edge on the adjacent cell — Google-Docs style edge-symmetric border editing.

Schema-free: only attribute updates via `tr.setNodeMarkup`.

    style: string;
