data: include qwen35-swebench-50sess trace under third_party/traces/

Add the 54 MB SWE 50sess replay trace to the repo under
third_party/traces/ so it travels with `git clone` to GPU nodes that
can't reach the sandbox network. Previously the trace only lived under
outputs/ which is .gitignored.

Whitelist third_party/traces/ in .gitignore (same pattern as the
existing third_party/sglang/ allowlist).

After cloning on a new host, either symlink the file into outputs/ for
backward compatibility:
  ln -sf ../third_party/traces/qwen35-swebench-50sess.jsonl \
         outputs/qwen35-swebench-50sess.jsonl
or update sweep scripts to point --trace at third_party/traces/.

README in the new directory documents the file's lineage
(SiCo → SiBench → audit.jsonl → convert_audit_to_trace.py) and the
100 MB GitLab single-file limit warning for future trace additions.

+
+## 使用方法
+
+Replay 端的 trace 路径由 CLI flag `--trace` 指定。默认 sweep 脚本里指向
+`outputs/qwen35-swebench-50sess.jsonl`——为了向后兼容老脚本，**建议在 clone 后
+软链接一份过去**：
+
+```bash
+mkdir -p outputs
+ln -sf ../third_party/traces/qwen35-swebench-50sess.jsonl \
+       outputs/qwen35-swebench-50sess.jsonl
+```
+
+或者直接改 sweep 脚本里 `--trace` 路径指向 `third_party/traces/...`。
+
+## 添加新 trace
+
+如果未来加新 trace 文件（如 `codex_swebenchpro` 转换后的版本），直接放本目录，
+更新本 README 的清单即可。**别把超过 100 MB 的单文件直接 git add**——GitLab
+默认对未启用 LFS 的单文件有 100 MB 限制。
