[WIP] Fix lint errors in Go code

[Copilot]

Plan to Fix Lint Go Error

• Investigated the lint-go CI failure
• Identified the root cause: golangci-lint v2.7.2 requires Go ≤ 1.24, but go.mod specifies Go 1.25.0
• Downgrade Go version from 1.25.0 to 1.24 in go.mod
• Verify no Go 1.25-specific features are used in the codebase
• Run golangci-lint locally to ensure it passes
• Test build and basic functionality

Root Cause: The error message "the Go language version (go1.24) used to build golangci-lint is lower than the targeted Go version (1.25.0)" indicates a version mismatch between the golangci-lint binary (built with Go 1.24) and the project's Go version requirement (1.25.0).

Solution: Downgrade go.mod to Go 1.24 since:

1. No Go 1.25-specific features (like iter package) are being used
2. golangci-lint v2.7.2 in go.mod was built with Go 1.24
3. This will immediately fix the CI lint failure
