## Description

<!-- SECTION:DESCRIPTION:BEGIN -->
Cmd+Left/Right (arriving as Home/End) jumped to the top/bottom of the document, and Ctrl+Up/Down moved to line start/end — backwards from macOS convention. Home/End now move to line edges; Ctrl+Home/Ctrl+End (what Ghostty's cmd+up/cmd+down send: CSI 1;5H / CSI 1;5F) move to document edges, with Ctrl+Up/Ctrl+Down as aliases. Shift variants follow. Bubbletea's Key struct has no Cmd/Super modifier, so Cmd can only ever reach glint as a terminal-emitted escape sequence — README now documents the four sequences plus Ghostty/iTerm2/Terminal.app config.
