Add dotenv.org feature (dotenvx via bun)

[Copilot]

Adds a new devcontainer feature for dotenvx — the next-gen dotenv CLI with multi-environment and encrypted .env support — installed globally via bun install -g @dotenvx/dotenvx.

Changes

• src/dotenv.org/ — new feature following the bun install template (critique.work as reference):
  • devcontainer-feature.json — id dotenv.org, v1.0.0, version option defaulting to latest
  • install.sh — auto-installs bun to /usr/local if absent, then runs bun install -g @dotenvx/dotenvx[@version]
  • NOTES.md — project link, description, install method
• test/dotenv.org/test.sh — verifies binary exists at /usr/local/bin/dotenvx and executes
• README.md — new row inserted alphabetically between dolthub.com/doltgres and dozzle.dev

Usage

// devcontainer.json
{
  "features": {
    "ghcr.io/devcontainer-community/features/dotenv.org:1": {}
  }
}

Fixed in e1b9969. The root cause was that bun install -g creates a symlink to dotenvx.js which has a #!/usr/bin/env node shebang — but node isn't installed in the container. The fix resolves the symlink to the actual JS path, removes it, and writes a shell wrapper (#!/bin/sh\nexec bun run "..." "$@") so dotenvx runs via bun instead.
