feat(cli): add focus-monitor-at-cursor cmd

This commit adds a new komorebic command, focus-monitor-at-cursor, which
can optionally be chained with the focus-workspace command in
keybindings to reproduce the previous default behaviour of auto-focusing
whichever monitor the cursor was on before attempting to change the
focused workspace.
