note: Tool registration requires initialized MCP stdio lifecycle. `00001KVHR3WRY` is queued and depends on `00001KVHR3WRF`; leave this Ticket queued until lifecycle is closed.

author: yoi-orchestrator


summary: Initialized MCP stdio lifecycle clientを使って `tools/list` を実行し、server-provided tool metadataを untrusted dataとして検証・正規化し、既存 `pod::feature` / ToolRegistry path経由で namespaced Yoi tools として登録する。This Ticket does not implement `tools/call` execution or resources/prompts.

role_plan: Orchestrator は acceptance records を commit 後、専用 implementation worktree `.worktree/00001KVHR3WS6-mcp-tool-registration` を作成し、Coder をその child worktree への narrow write scope で起動する。Coder 実装後、Reviewer が tools/list pagination/bounds、untrusted metadata/schema normalization、namespaced ToolRegistry registration、no tools/call execution、no resources/prompts registration を確認する。
