perf!: various refactor to maximize performances

This commits adds the following:
- repository, local and remote, are now cloned (faster for local
  repository instead of using `PlainOpen`)
- commits are now parsed one by one and not in bulk (around 1.5% faster)
- branch, monorepo and rules flags types are updated to "JSON string"
- AppContext has been moved to its own internal package
- parser now only uses AppContext for configuration

BREAKING CHANGE
