Fix Strict Typing Compatibility

Description

• Ship generated .d.ts declarations (dist/types/) and a generated type entry (dist/index.d.ts) instead of pointing consumers' type resolution at the raw .ts source. This stops downstream TypeScript projects from compiling ULabel's source under their own (stricter) tsconfig.
• Stop publishing the src/ directory in the npm package (files now ships dist/ only).

PR Checklist

• Merged latest main
• Version number in package.json has been bumped since last release
• Version numbers match between package package.json and src/version.js
• Updated documentation if necessary (currently just in api_spec.md)
• Added changes to changelog.md

Pull request overview

This PR updates the package’s TypeScript type publishing strategy to avoid downstream projects type-checking ULabel’s raw src/*.ts under stricter consumer tsconfig settings, by shipping generated declaration output under dist/ and pointing types/exports there.

Changes:

• Add a dedicated tsconfig.types.json and build steps to emit declarations to dist/types/ plus a generated dist/index.d.ts entry with shims.
• Update internal type-only imports to resolve via explicit ../index paths and tighten the type test harness to strict: true.
• Adjust npm publishing metadata to ship dist/ only and route type resolution to dist/index.d.ts.
