Add tsconfig.json for TypeScript 5.9.3 package and update compile script

- Introduce a tsconfig.json with tailored compiler options for the 5.9.3 package
- Modify compile script to copy tsconfig.json before running tsc without arguments
- Update .gitignore to ensure tsconfig.json is not ignored

This aligns with previous changes to run tsc without explicit file args and ensures consistent compilation settings.
