/**
 * Per-user AI chat module (§6.1).
 *
 * AiModule supplies AiService + AiSettingsService. TokenModule supplies
 * TokenService for minting the per-user loopback access token (§15[C1]). The
 * AiChatRepo / AiChatMessageRepo / PageEmbeddingRepo / SpaceMemberRepo /
 * PagePermissionRepo come from the global DatabaseModule; the UserThrottlerGuard
 * + AI_CHAT throttler come from the global ThrottleModule registered in
 * AppModule. EmbeddingModule hosts the vector-RAG indexer + AI_QUEUE consumer
 * (§6.7 stage D); importing it here boots the processor with the app.
 *
 * ShareModule (ShareService) + SearchModule (SearchService) are imported for the
 * ANONYMOUS public-share assistant (PublicShareChatController), whose read-only
 * tools scope every lookup to a single share tree.
