- Rewrite cursor_test.go to use the current GlyphLayout-based API
instead of the deleted byteOffsetToLineCol function
- Add guard for empty/missing layout slices in SetCursorFromPoint
to prevent index-out-of-range panic on empty documents
- Add missing Advance field to e2e test GlyphLayout initialization
- Add cmd/pad/pad binary to .gitignore
- Replace gtx.Event(nil) with key.Filter{Focus: focusedID} and
key.FocusFilter{Target: focusedID} so Gio correctly routes key
and edit events to the focused editor text field.
- Convert EditorState.CursorPosition (byte offset) to line/column
coordinates for accurate cursor rendering.
- Add debug logging in HandleKeyDown and HandleCursorMove.
