feat(cli): add ahk flag to static config start cmd

This commit introduces a new --ahk flag to the start command, which
works similarly to the --whkd, and attempts to load an ahk key binding
configuration script on startup.

The attempt is made from within the komorebic process, rather than the
komorebi process.
