Parallelize hooky lints

Right now, `hooky lint` runs completely serially. Parallelize the operations as much as possible

Start by tracing the `hooky lint` command and how it runs pre-commit hooks. Determine which lint operations can safely run concurrently and define how completion and failures should be reported. Done means `hooky lint` no longer runs all operations serially while preserving correct results.
