✨ feat(vscode): 提交代码按钮实时显示进度并预检 git 身份

- spawnClaude 新增 onProgress 回调，给了回调就改走 stream-json 逐行输出，按行解析出工具调用 / 回复文本
- 新增 claudeProgress 把每行 NDJSON 压成可读进度短语
- 提交前先读 git user.name / user.email，缺失直接提示，不再让 claude 白跑
- 运行期间用带转圈的 toast 滚动显示进度，完成后带上 claude 的结果摘要

+ * 把 `claude -p --output-format stream-json --verbose` 吐出的每行 NDJSON
+ * 压缩成人能看懂的进度短语，供长任务（如提交代码）实时展示。
+ *
+ * 只关心 assistant 消息里的 `tool_use` 和 `text` 块，其它行（system / user /
+ * result / thinking 块 / 坏 JSON）一律返回空数组，调用方无需再做判断。
