[Copilot]

Expands DevMagic's dev container from a Node.js/TypeScript-only environment to a multi-language setup by enabling four additional runtime features.

Changes

• .devcontainer/devcontainer.json
  • Added ghcr.io/rails/devcontainer/features/bun:1 (latest)
  • Added ghcr.io/devcontainers/features/python:1 (3.12)
  • Added ghcr.io/devcontainers/features/ruby:1 (3.4)
  • Added ghcr.io/devcontainers/features/go:1 (1.23)
  • Removed now-redundant commented-out stubs for python, ruby, and go

"features": {
  "ghcr.io/rails/devcontainer/features/bun:1": { "version": "latest" },
  "ghcr.io/devcontainers/features/python:1": { "version": "3.12" },
  "ghcr.io/devcontainers/features/ruby:1": { "version": "3.4" },
  "ghcr.io/devcontainers/features/go:1": { "version": "1.23" }
}

Original prompt

Update .devcontainer/devcontainer.json to include additional essential dev container features.

We want to expand the language/tooling support in DevMagic to offer a flexible, multi-language environment while keeping the base image minimal.

Please add the following features to the "features" object in .devcontainer/devcontainer.json:

1. Bun: Add the Bun feature (borrowing from the Rails devcontainer repository).

"ghcr.io/rails/devcontainer/features/bun:1": {
  "version": "latest"
}

2. Python: Add the official Python feature.

"ghcr.io/devcontainers/features/python:1": {
  "version": "3.12"
}

3. Ruby: Add the official Ruby feature.

"ghcr.io/devcontainers/features/ruby:1": {
  "version": "3.4"
}

4. Go: Add the official Go feature.

"ghcr.io/devcontainers/features/go:1": {
  "version": "1.23"
}

Make sure the JSON syntax remains valid and these are correctly added to the existing "features" block in .devcontainer/devcontainer.json.
