Summary

Add a .devcontainer configuration to enable consistent local development using VS Code Dev Containers.

Requirements

Create a .devcontainer/devcontainer.json file with the following configuration:

Base Image

• Use mcr.microsoft.com/devcontainers/go:1-1.25-bookworm to match the Go 1.25 requirement in go.mod
