- Rewrite main.js -> index.js as plain CJS (drop AMD/UMD wrapper)
- Add index.mjs ESM re-export for dual-module support
- Add index.d.ts TypeScript declarations
- Fix string deduplication bug: encode before dictionary lookup
- Serialize Date as ISO 8601 string instead of producing {}
- Use Array.isArray() directly, remove instanceof Array
- Remove dead code: _indexOfDictionary, _indexOf IE8 polyfill
- Dictionary uses objects for O(1) lookup (from merged PR Improve packing performance #27)
- Replace Makefile + .travis.yml with npm scripts + GitHub Actions (Node 18/20/22)
- Remove package.js (Dojo/Volo artifact)
- Modernize package.json: license, repository URL, engines >=14, exports field
- Migrate tests to assert.strict, drop expect.js, add Date and round-trip cases
- Update all Sapienlab references to SASUD, update contact email
- Rewrite README: remove Travis/volo/AMD, add ESM example, Web Worker note

Reposition jsonpack as a URL-safe JSON serializer sitting between encodeURIComponent (fast, expands data) and lz-string (best compression, slow decode). Add benchmark charts, when-to-use guidance, and bundle size.
Add TOKEN_DATE (-6) to the packed format. During pack, Date instances
are stored as ISO strings in the dictionary and marked with a sentinel
in the structure section. During unpack, the sentinel triggers
new Date(dictionary[index]) restoring the original type.
Previously: pack({d: new Date()}) -> unpack -> {d: 'ISO string'}
Now: pack({d: new Date()}) -> unpack -> {d: Date instance}
Old packed strings (without Date tokens) remain fully compatible.
