LGTM — no blocking issues found.

This is a clean upgrade of the H200 GPT-OSS TensorRT-LLM config from the dev image (gpt-oss-dev) to an official release candidate (v1.3.0rc5). The sed workaround removal and enable_block_reuse default change are both reasonable cleanups enabled by the new container version. Perf changelog is properly updated.
