Merge pull request 'feat(onboard/parity): L1 零模型三端检查 probe_client_parity，处置独立审查（P4a）' (#38) from feat/agent-client-parity-p4a into master

两边各自新增全局路由工具（probe_client_parity / register_project）：清单插入、
is_project_scoped_tool 排除、STRUCTURED_TOOLS 与摘要分支均保留双方；契约文档合并两段说明。
合并结果 cargo test 377 passed / 0 failed / 6 ignored，pnpm typecheck 通过。
