Subject: [PATCH] Fix Go version compatibility and golangci-lint config

- Change go.mod from 1.25.0 to 1.24.0 (available version)
- Format all Go files with gofumpt
- Comment out version: "2" in .golangci.yml (config version, not binary version)
- Install and use golangci-lint v1.64.8
- All linters pass successfully
