ci: switch from pre-commit to prek

[nstarman]

Summary

• Switches from pre-commit to prek, a drop-in, Rust-based reimplementation that reads the same .pre-commit-config.yaml — no hook changes needed
• Swaps the pre-commit dependency for prek wherever it's declared (nox lint group / dev group) and updates the nox precommit session (or CI action) to invoke prek instead
• Regenerates uv.lock to match

This mirrors the same swap already merged in unxt#929, coordinax#881, jaxmore#26, quaxed#213, and quax-blocks#64.

Note: this repo's .pre-commit-config.yaml still has pre-commit.ci's ci: autoupdate block. Disabling the pre-commit.ci GitHub App integration itself is a setting on pre-commit.ci / the repo's installed-apps page, not something a code change can do — worth doing once this merges, to avoid running checks twice.

Test plan

• uv lock resolves cleanly with prek replacing pre-commit
• Verified prek run --all-files (and no-commit-to-branch specifically) locally against this org's existing .pre-commit-config.yaml format

🟢 Approval recommended

The dependency/tooling swap is consistent across pyproject, lockfile, nox, and CI, and the CI action input name (extra-args) matches the action’s published interface.

Pull request overview

This PR switches the repository’s lint/format hook runner from pre-commit to prek (a compatible runner for the same .pre-commit-config.yaml) across local tooling (nox), dependency declarations, and CI.

Changes:

• Replace pre-commit with prek in dependency groups and regenerate uv.lock accordingly.
• Update the nox lint session to install and invoke prek.
• Update CI to run hooks via j178/prek-action.
