chore(studio): remove dead BookFormCard create_book toolCall path

ChatPage 通过 /api/v1/agent 走的是 pi-agent loop，工具集是
sub_agent / write_truth_file / read / edit / grep / ls 等，从来不会
返回 toolCall.name === "create_book"。BookFormCard 的渲染条件因此
永远不成立，相关的 pendingBookArgs / bookCreating / handleCreateBook /
createProgress 一整套 store 状态也都是死代码。

实际建书走 BookCreate 独立表单页 → POST /api/v1/books/create，与
本次清理无关；CLI 仍在用的 develop_book / CREATE_BOOK_TOOL /
developBookDraft 全都在 core 端，未触动。
