EntelligenceAI PR Summary

Upgrades the kotlinx-serialization-json dependency to the latest patch release (1.8.1) in the Gradle version catalog.

• Bumped kotlinx-serialization-json from 1.8.0 → 1.8.1 in gradle/libs.versions.toml

---

Confidence Score: 5/5 - Safe to Merge

Safe to merge — this PR performs a minimal, isolated patch version bump of kotlinx-serialization-json from 1.8.0 to 1.8.1 in gradle/libs.versions.toml, with no logic, API, or behavioral changes introduced. The change is confined to a single line in the version catalog and carries extremely low risk given the patch-level nature of the upgrade. No review comments were generated and no pre-existing unresolved issues exist.

Key Findings:

• The change is a single-line patch version increment (1.8.0 → 1.8.1) in gradle/libs.versions.toml, which is the correct and only place such a version should be managed in a Gradle version catalog setup.
• Patch releases of kotlinx-serialization-json typically contain bug fixes and minor improvements without breaking API changes, making this a low-risk dependency update.
• No heuristic analysis flagged any issues, no review comments were generated, and all changed files were reviewed — coverage is 100% with zero concerns.
