Review Details

Files: Dockerfile, Dockerfile.alpine

Critical Finding: This PR fixes a build compatibility issue. The file requires Go 1.25.5, but the current base branch Dockerfile uses Go 1.20, causing build failures.

Changes:

• : golang:1.20 → golang:1.25 (required to match go.mod)
• : golang:1.16.15-alpine3.15 → golang:1.19.3-alpine3.15

Security Benefits: Updates provide latest security patches and improvements.

Build Compatibility: Makefile uses standard commands compatible with Go 1.25.
