Highlights

0.4.2 is mainly about making prek run faster in large repos.

prek now does less git diff work. After hooks run, prek uses diff checks
to detect files changed by hooks. If a hook modifies files, prek marks that hook
as failed. That is important, but full diff snapshots can be slow in big repos,
especially when they happen after every hook group.

We skip the expensive diff path in two common cases: built-in hooks that prek
knows are read-only, and clean worktrees where a cheap dirty check is enough
unless a hook actually changes files. In the right large-repo workload,
skipping that work can make runs up to 10x faster.

Workspace mode is faster too. Hooks have historically been too serial.
Priority-based concurrency helped, but it required users to choose good
priority values. Now sibling projects at the same workspace depth run in
parallel automatically. Their files do not overlap, so this is safe and needs
no extra config. For multi-project workspaces, this can dramatically reduce
total hook time.
