Phase 1 Foundation - Hoodie Schema Wrapper Implementation

Description
This sub-issue tracks the implementation of the core HoodieSchema wrapper classes that serve as the foundation for all subsequent schema consolidation work. These classes provide a Hudi-native API while maintaining full binary compatibility with existing Avro Schema usage through delegation patterns.

Problem Statement
Before schema consolidation can begin, we need wrapper classes that:

Provide a clean HoodieSchema API that mirrors Avro Schema functionality.
Maintain 100% binary compatibility through delegation to underlying Avro objects
Support all existing Avro Schema operations without behavioral changes.
Enable gradual migration through method overloading and conversion utilities
Include comprehensive utility methods for table schema operations

Start by reviewing the existing Avro Schema API and the issue's requirements for HoodieSchema wrapper classes. Determine the required wrapper types, delegation behavior, compatibility expectations, overloads, conversion utilities, and table-schema operations. Done means the core wrappers provide the stated Hudi-native API while preserving existing Avro behavior.
