Summary of Changes

1. Refactor import maps generation to provide full href, prefixed with a /~/
2. Fully extend use of import.meta.resolve throughout Greenwood (no hardcoded node_modules location assumptions 💯 )
3. Added a main entry point to @greenwood/cli's package.json (so things like hashing utils and static router can get resolved with import.meta.resolve)
4. Was able to remove hacky local monorepo workaround from rollup.config.js 🏆
5. Now that we are using import.meta.resolve don't need to copy node_modules libs into test cases anymore (although still needed it for context / theme packs, but can look into those later)

Documentation

1. track additional considerations - improve documentation around referencing scripts, styles, and import map diagnostics www.greenwoodjs.dev#144

   • hosting patterns, e.g. public-hoist-pattern[]=@lit-labs/*, wc-compiler for PNPM users
   • Add example demo links to website for Lit ecosystem demos
   • recommendations around using /node_modules vs bare specifiers, vs ../../deep/path/to/file.css
   • exports / import.meta.resolve call out examples
     • (no default in exports map) - ERR_PACKAGE_PATH_NOT_EXPORTED when package is called using import.meta.resolve vercel/geist-font#150
     • (no main) - https://unpkg.com/browse/[email protected]/package.json
