### Changes:
- **verify-package-size.js**:
- Added a CLI script to calculate and display the estimated package size.
- Integrated support for parsing `.npmignore` and `package.json` `files` patterns.
- Outputs total package size and lists the largest files included.
- **.npmignore**:
- Introduced an `.npmignore` file to exclude unnecessary development, configuration, and large files from the package.
- Added patterns for source maps, development files, configuration files, and artifacts.
- **package.json**:
- Updated the `files` array to include new patterns for distribution files (`.js`, `.d.ts`, `types`).
- Improved package inclusion accuracy with precise file patterns.
### Purpose:
Introduced a new utility to provide quick insights into the package size for better maintenance and optimization. Optimized `.npmignore` and `files` configurations in `package.json` to exclude irrelevant files, ensuring a smaller, cleaner package distribution.
