Dependency Bump Evaluation

Version change: 4.28.4 -> 4.28.9 (patch)
Semver bump type: patch (5 patch releases)

Changes:

• 4.28.9: Improve or parsing performance
• 4.28.8: Fixed including kaios in baseline queries
• 4.28.7: Improved parsing performance, fixed unbounded memory growth, fixed prototype write issue
• 4.28.6: Fixed Electron version queries
• 4.28.5: Fixed > and >= queries

Breaking changes: None

Security concerns: None — the 4.28.7 release includes a prototype write fix and memory growth fix, which are security-positive improvements

Impact on codebase: browserslist only appears in lockfiles as a transitive dependency. No direct usage in source code. Change is limited to tests/workflows/yarn.lock (28 lines added, 28 removed)

Recommendation: SAFE TO MERGE

Notes: CI checks (CodeQL, tests) are still in progress at time of review. All completed checks passed. Given the change is a lockfile-only patch bump of a transitive dev dependency in the test workflows directory, risk is minimal.
