google-labs-jules[bot] 06d8a3bcc3 feat: Rewrite Keyfleur in TypeScript for npm publishing
This commit completes the full rewrite of the Keyfleur application from Python to TypeScript.

Key changes include:
- Core logic (themes, syllable generation, key generation modes) ported to TypeScript.
- CLI interface implemented using yargs.
- Comprehensive unit tests added using Jest, covering core functions and basic CLI operations.
- README.md updated with new installation (npm), usage instructions, and development guide.
- package.json configured for npm publishing, including:
    - Package name: "keyfleur"
    - Version: "1.0.0"
    - CLI command: "keyfleur"
    - Build and test scripts, including "prepublishOnly".
    - Essential metadata for npm.

The application is now structured as a modern TypeScript package, ready for building, testing, and publishing to npm.
