⚡ Bolt: [performance improvement] Avoid deep clones during OpenAPI parsing

[cloudesize67-cmd]

💡 What: Refactored the OpenAPI parser component-loading loop to deserialize objects directly from JSON and YAML values by reference (using T::deserialize(&value)) rather than cloning the entire subtree (serde_json::from_value(value.clone())).

🎯 Why: In large OpenAPI specifications, the components schemas, parameters, and responses can be massive deeply-nested maps and arrays. Cloning them entirely just to deserialize into strongly-typed structures is an expensive O(N) allocation bottleneck that slows down parsing and wastes memory. Since both &serde_json::Value and &serde_yaml::Value implement the Deserializer trait natively, referencing the DOM avoids this overhead.

📊 Impact: Significantly reduces allocations and deep cloning latency in the parser during the initial context population phase for very large API specs.

🔬 Measurement: Review the codebase, specifically xdk-openapi/src/parser.rs, and run cargo test --all and make check. They successfully verify that the logic is mathematically identical without mutating intermediate values.
