- workspace-nav-studio: return null while isLoading so the "工作室" group
no longer briefly mounts and then unmounts when getTokenByEmail returns
"用户不存在" (404). Skeleton branch became dead code, removed.
- studio/hooks: switch all three token queries from retry: 1 to false —
account-not-found is a permanent error; retry just doubled isError latency.
- env: drop VITE_STUDIO_ENABLED everywhere (env.ts + 7 env files +
workspace-nav-chat-list). Sidebar availability is now decided at runtime
by token success instead of a build-time flag.
- env: add VITE_AIPI_PRESENT_URL + VITE_AIPI_KNOWES_URL for the document
upload popup's A-system jump + B-system knowledge iframe; reuse the
existing VITE_AIPI_KNOWLEDGE_URL for the Y-system iframe.
- document-upload-popup: replace 8 hardcoded URLs (6 present, 1 knowes,
1 knowlibrary) with the corresponding env vars.
