feat(deepLinks): implement comprehensive deep linking system

- Add type-safe deep link parameter validation using Zod
- Implement consistent error handling across all deep link routes
- Add support for query parameters in deep links
- Create comprehensive deep linking documentation
- Add logging for deep link operations

Security:
- Validate all deep link parameters before processing
- Sanitize and type-check query parameters
- Add error boundaries around deep link handling
- Implement route-specific parameter validation

Testing:
- Add parameter validation tests
- Add error handling tests
- Test query parameter support
