Automated Review

Tests: All CI checks passed.

Summary: This is a routine Renovate dependency update bumping org.slf4j:slf4j-api and org.slf4j:slf4j-simple from 2.0.7 to 2.0.18.

Assessment: Safe to merge.

• The change is a single-line version bump in settings.gradle.kts (the version catalog entry used by both SLF4J artifacts).
• SLF4J 2.0.x is a stable minor series; patch releases in this range contain only bug fixes and no API changes.
• No code changes required — SLF4J is a logging facade with a stable API, and connector/server code uses it only via LoggerFactory calls.
• CI passed, confirming no runtime or compile-time regressions.

PR Review

Tests: Passed ✓

Change: Bumps slf4j (both slf4j-api and slf4j-simple) from 2.0.7 to 2.0.18 via a single version ref in settings.gradle.kts.

Assessment: This is a clean, low-risk patch/minor update. The slf4j 2.0.x line is stable and these releases are primarily bug fixes and minor improvements. The version catalog approach correctly updates both artifacts atomically via a single version("slf4j", ...) ref, ensuring they stay in sync. No API changes to worry about in this range.

No issues found. Safe to merge.
