Pull Request Overview
This PR adds support for emitting .d.cts.map and .d.mts.map declaration map files alongside CommonJS and ES module declaration files. The implementation ensures proper file naming, source mapping URLs, and file field references in the map files.
- Adds logic to rename declaration map files with appropriate extensions (
.d.cts.map,.d.mts.map) - Updates declaration map content to reference correct declaration file names
- Modifies source mapping URLs in declaration files to point to correctly named map files
