feat(Support): Add number parsing methods to Number class

Add three new methods to the Number class for parsing numeric strings:
- parse(): Parse string to number based on format type
- parseInt(): Parse string to integer with locale support
- parseFloat(): Parse string to float with locale support

These methods leverage the PHP Intl extension's NumberFormatter to provide
locale-aware number parsing capabilities.
