Code Review
This pull request introduces a comprehensive streaming parser for A2UI (v0.8 and v0.9), including a base StreamingParser class and version-specific implementations. It also enhances schema management with new pruning capabilities for components, messages, and common types, and improves validation logic with more precise error reporting. Feedback includes suggestions to optimize regex compilation and object creation for better performance, handling potentially destructive path logic in v0.8, and adding checks for duplicate component IDs to ensure unambiguous error paths.

Implements custom JSON-path validation error string construction for v0.9 payloads in Kotlin, matching Python exactly. Validates messages individually via sub-validators and iterates component arrays to construct precise path prefixes.
