Greptile Summary

This PR bumps go.uber.org/zap from v1.27.1 to v1.28.0 in the backend module. The release adds zapcore.CheckPreWriteHook and CheckedEntry.Before (additive, no breaking changes), and zap internally migrated its own YAML dependency from the archived gopkg.in/yaml.v3 to the officially maintained go.yaml.in/yaml/v3, which appears as a new entry in go.sum.

Confidence Score: 5/5

Safe to merge — minor version bump with only additive changes and no breaking API modifications.

This is a routine dependency bump with a clean minor version increment. The single enhancement is purely additive (a new hook API), and the new transitive dep (go.yaml.in/yaml/v3) is the officially maintained successor to gopkg.in/yaml.v3. No security, logic, or compatibility concerns.

No files require special attention.

Important Files Changed

Filename	Overview
backend/go.mod	Bumps go.uber.org/zap dependency from v1.27.1 to v1.28.0 — minor version, additive-only change.
backend/go.sum	Updates zap hashes and adds go.yaml.in/yaml/v3 v3.0.4 as a new transitive dependency (zap's own internal dep migration from archived gopkg.in/yaml.v3).
