Move build outputs to distribution folder

[Copilot]

• Update tsconfig.json to output to distribution/ folder
• Update package.json exports and files to reference distribution/
• Update .gitignore to exclude distribution/ folder instead of individual build files
• Update test imports that reference ../index.js to use ../distribution/index.js
• Run build to generate files in new location
• Run tests to verify everything works (all 34 tests pass)
• Verified the module can be imported successfully from distribution/
• Remove trailing comma from tsconfig.json compilerOptions

Summary: Successfully moved all build outputs from the root directory to the distribution/ folder. Source files were already in the source/ directory. All tests pass and the module imports correctly.

Original prompt

Move all source files in the repository into a folder named 'source' and ensure that output files are directed into a folder named 'distribution'. Update any configurations, imports, or scripts in the repository to reflect these changes. Test the changes to confirm that the project functions correctly with the new folder structure.
