Greptile Summary

This is a routine Dependabot patch bump of the dev dependency @vitest/coverage-v8 from 4.1.8 to 4.1.9. The lock file is updated accordingly with new integrity hashes and a handful of transitive dependency bumps.

• package.json updates the version specifier to ^4.1.9; the lock file resolves @vitest/coverage-v8@4.1.9 alongside its updated transitive deps (@vitest/utils, @vitest/pretty-format, ast-v8-to-istanbul, obug, semver, @types/estree)
• vitest itself stays at 4.1.8, which means @vitest/coverage-v8@4.1.9's declared peer requirement of vitest: 4.1.9 is technically unmet — pnpm still resolved the pair (shown in the lock file snapshot key 4.1.9(vitest@4.1.8)), so no install failure occurs, but upgrading vitest to 4.1.9 as well would keep the ecosystem in sync

Confidence Score: 5/5

Safe to merge; this is a dev-only patch release for the coverage reporter with no changes to production code.

The bump is limited to a test-coverage dev dependency and its transitive chain. All changed packages are patch-level releases. The only minor wrinkle is that vitest stays at 4.1.8 while @vitest/coverage-v8@4.1.9 now declares vitest: 4.1.9 as a peer — pnpm resolved them together without error, and the two packages are part of the same release monorepo so patch-level skew is typically benign. No production code or runtime dependencies are affected.

No files require special attention; both changes are mechanical lock-file updates.

Important Files Changed

Filename	Overview
package.json	Dev-dependency version specifier bumped from ^4.1.8 to ^4.1.9 for @vitest/coverage-v8; no other changes.
pnpm-lock.yaml	Lock file updated to resolve @vitest/coverage-v8@4.1.9 with new integrity hashes; transitive deps (@vitest/utils, ast-v8-to-istanbul, obug, semver, @types/estree) also bumped to their latest patch versions. vitest itself remains at 4.1.8, creating a minor peer-version skew.
