Add a toggle for crash capture (#6824)

Crash capture stays on by default, but Trigger > Toggle > Crash Capture (or
`omarchy toggle crash-capture`) now turns the watcher off. The toggle writes the
usual flag file and stops the unit for this session; the unit checks the same
flag with ConditionPathExists, so the choice survives a logout without the unit
having to be disabled.
