TXT Sheets v0.2.9

Drag to select multiple cells, rows, and columns, with automatic scrolling at the grid edges. Right-click a selection for cut, copy, paste, row/column insertion and deletion, cell shifting, clearing contents, and Undo/Redo.

Selection is preserved when right-clicking inside a range. Bulk changes are undoable, formula references follow structural edits, and merged-cell editing remains intact. Unsafe cell shifts that would split merged cells or formula ranges are blocked.

Validation: 64 automated tests, production build, and Electron drag selection, context menu, clipboard, keyboard, fill, save/close, structural editing, and save/reopen checks.
