Phase 14: Core Method Call Migration

Replace all method calls from deprecated Avro Schema methods to new HoodieSchema equivalents in core packages.

Scope: hudi-common, hudi-io packages

Changes: Replace Schema.parse() with HoodieSchema.parse(), Schema.createRecord() with HoodieSchema.createRecord(), all schema operations to HoodieSchema equivalents

Strategy: Automated refactoring where possible, manual verification of complex cases, comprehensive testing after each module

Constraints: Maintain identical behavior, validate all test suites pass, keep serialization boundaries unchanged
Files: All hudi-common and hudi-io classes using schema operations

Start by locating schema operations in the hudi-common and hudi-io packages, focusing on classes that call the deprecated Avro Schema methods. Review the automated refactoring candidates and manually verify complex cases module by module. Done means all calls use HoodieSchema equivalents, behavior and serialization boundaries remain unchanged, and every test suite passes.
