Use `--no-auto-install` by default when executing `run` hooks

⚡ Summary

Hooks are triggered when executing git commands like git commit
When lefthook is executed it automatically check if the hooks are installed

This is I believe useless as if the hooks were triggered it means the hooks are installed

Behavior and configuration changes

When lefthook run is executed via a hook dont check if hook is installed

Hey @cgaube , there is a small nuance. You may change the global settings of the config which affect the script in the git hooks, so the sync is required. Lefthook also supports the flow when you only do lefthook install once and then it keeps tracking the changes of the config file without manual lefthook install for convenience.

Also nothing will be installed if not required because lefthook calculates the hashsum of the config file and skips syncing hooks if nothing changed in the main config file.

So, this implicit installation step does not affect the execution time a lot, but reduces the need to manually install the hooks every time you change the configuration or add a new hook.

Gotcha, this is indeed helpful.

I would still love to be able to disable this behavior via configuration file though :)

Closing this issue since a small convenience wins the small optimisation benefits (from my perspective)
