allowFrom and ignoreFrom with callback functions

[tups]

This pull request enhances interact.js with callback function support for allowFrom and ignoreFrom options, providing developers with powerful programmatic control over interaction permissions.

Key Features Added

• Callback Support: Both allowFrom and ignoreFrom now accept callback functions with signature (targetNode: Node, eventTarget: Node) => boolean
• Enhanced Type Safety: Updated TypeScript definitions across core packages
• Comprehensive Examples: Added 3 interactive demo pages showcasing different use cases
• Full Test Coverage: Added test suites for both allowFrom and ignoreFrom callback functionality

New Examples

• ignoreFrom-callback/ - Basic callback usage with conditional ignore logic
• allowFrom-callback/ - Role-based access control demonstration
• combined-callbacks/ - Advanced example combining both options

Technical Changes

• Updated type definitions in @interactjs/core, @interactjs/auto-start, and related packages
• Enhanced Interactable.testAllow() and Interactable.testIgnore() methods with function support
• Maintained full backward compatibility with existing string/element selectors

This enhancement enables sophisticated interaction control scenarios like role-based permissions, conditional drag handles, and complex UI state management while preserving the library's existing API.
