发布 TraceFetch 1.0.0：统一 Agent 搜索产品

[estelledc]

What\n\n- 发布 TraceFetch 1.0.0：统一本地、公开网络与显式 Provider 搜索入口\n- 默认输出稳定的 Agent JSON 契约，并保留 0.1 兼容调用\n- 增加受限命令 Provider 协议、敏感范围 fail-closed 约束与 JSON Schema\n- 增加版本一致性检查、构建验证及 GitHub Release 工作流\n- 移除对 intern-journal 的产品级耦合，改为通用 workspace 示例\n\n## Why\n\nTraceFetch 需要从仓库内实验升级为可独立安装、可验证、可被其他 Agent 项目复用的搜索产品。\n\n## Impact and risk\n\n- 默认搜索仅访问本地 workspace；公开网络必须显式选择 scope\n- account/internal Provider 必须显式授权，internal scope 必须隔离运行\n- Provider 使用固定 argv 与 stdin/stdout JSON，不经过 shell\n- 1.0.0 首发范围是 GitHub Release；本 PR 不声明 PyPI 发布、SLA 或全网覆盖\n\n## Checks\n\n- 全新克隆：uv lock --check
