## Title

    Proposed fix: [Wrangler build] 'The package "fs" wasn't found on the file system but is built into node' when a Worker imports Node built-ins without nodejs_compat

## Body

    Recommended action: Add compatibility_flags = ["nodejs_compat"] with compatibility_date >= 2024-09-23 (per current docs, dates >= 2026-08-04 enable Node.js compat by default); do not use legacy node_compat.
    
    Option: Enable nodejs_compat with a recent compatibility_date [evidence: official_recommended_action]
    Applies when: Workers importing Node built-ins
    Steps:
    1. set compatibility_date to >= 2024-09-23
    2. add compatibility_flags: ["nodejs_compat"] (unless date >= 2026-08-04)
    3. remove node_compat
    Expected: Bundling resolves node built-ins
