refactor: migrate to node16 module resolution for TypeScript 6.0 compatibility

Switch module and moduleResolution from commonjs/node to node16/node16
across all three tsconfig files. Add explicit .js extensions to all
relative imports (static and dynamic) in src/ and test/.

This unblocks the TypeScript 6.0 upgrade (Dependabot PR #21) which
deprecated moduleResolution=node10.

Closes #22
