Code Review

This pull request introduces a comprehensive streaming parser for A2UI, supporting both v0.8 and v0.9 specifications. Key additions include the StreamingParser hierarchy, a SchemaInspector for heuristic component detection, and a TopologyAnalyzer for reachability analysis. The A2uiCatalog was also updated with logic to prune unused common types. Review feedback highlights several critical performance concerns in the parser implementation, such as inefficient string concatenation in buffers, frequent regex compilation during metadata sniffing, and redundant serialization when tracking yielded components.

The unit tests should be covered by the conformance tests in catalog.yaml.

If not, we should update the conformance tests.
