W17: close 9 audit findings — atomic pointers, SSE robustness, leak fix, verification (W17.1-W17.4)
Some checks failed
CI / Determine matrix (push) Has been cancelled
CI / ${{ matrix.os }} / ${{ matrix.build_type }} (push) Has been cancelled

- W17.1 (曹武): Verify F-13.3-1/2/3 all fixed by W14.1, close 3 findings (1 CRITICAL + 1 HIGH + 1 MEDIUM)
- W17.2 (赵码): Fix F-13.2-3 SSE [DONE] sentinel trimming + F-13.2-4 g_host/g_http/g_config atomic pointers in deepseek_plugin
- W17.3 (王测): Verify 4 W14 findings (F-13.1-1/4, F-13.2-1/2) + F-11.7-2 confirmed fixed, close 5 findings
- W17.4 (马奔): Fix F-13.1-2 response_body leak on error path + F-13.1-3 g_host/g_http atomic pointers in anthropic_plugin

Build 0 error, ctest 4/4 pass, metadata check clean.
