• #12466 caf9b11 Thanks @petebacondarwin! - Add MINIFLARE_CACHE_DIR environment variable and smart cache directory detection

  Miniflare now intelligently detects where to store its cf.json cache file:

  1. Use MINIFLARE_CACHE_DIR env var if set
  2. Use existing cache directory if found (node_modules/.mf or .wrangler/cache)
  3. Create cache in node_modules/.mf if node_modules exists
  4. Otherwise use .wrangler/cache

  This improves compatibility with Yarn PnP, pnpm, and other package managers that don't use traditional node_modules directories, without requiring any configuration.
