The Editor component now accepts TUI as the first constructor parameter, enabling it to query terminal dimensions. When content exceeds available height, the editor scrolls vertically keeping the cursor visible. Features: - Max editor height is 30% of terminal rows (minimum 5 lines) - Page Up/Down keys scroll by page size - Scroll indicators show lines above/below: ─── ↑ 5 more ─── Breaking change: Editor constructor signature changed from new Editor(theme) to new Editor(tui, theme) fixes #732
