Turns out project locks would get created and only stick around for a short duration as the default move constructor was letting the og object free the lock.
But if you crashed kicad or managed something weird, you can get a lock file with no override prompt which also creates confusion as some stuff gets set read only.
So lets just fix this up.
- Implement move constructor on lockfile so that the old object will no longer free the lockfile
- Move lock ownership to the project itself, just slightly less weird to handle for the lock override
- Implement the override lock prompt
