chore(repo): catch formatting in pre-commit before CI

[izadoesdev]

The pre-commit hook ran check-types and policy-lint but never ultracite check, so formatting issues (like the #590 one-liner that failed the release lint on #587) only surfaced in CI. Adds a staged-file ultracite check step to lefthook's pre-commit, mirroring CI's Lint job.

Verified: staged a misformatted file and ran bunx lefthook run pre-commit — the new format command fails with Run: bun run format; clean files pass.

Summary by cubic

Add ultracite formatting checks to lefthook pre-commit so formatting issues are caught locally instead of failing in CI. The hook runs bunx ultracite check {staged_files} across JS/TS/JSON/CSS and fails with “Run: bun run format” to guide fixes.

Greptile Summary

The PR adds an Ultracite check for staged source and configuration files to the pre-commit hook, allowing formatting and lint failures to surface before CI.

• Runs bunx ultracite check against matching staged files.
• Provides remediation guidance through the hook’s failure message.

Confidence Score: 5/5

The PR appears safe to merge, with the new hook using the repository’s existing pinned Ultracite tooling.

The added command applies the same Ultracite check used by CI to relevant staged files, and no concrete build, hook-execution, or coverage failure remains.

Important Files Changed

Filename	Overview
lefthook.yml	Adds a staged-file Ultracite pre-commit check consistent with the repository’s existing lint and formatting scripts; no actionable defect was established.
