feat: HLS streaming, transcripts, agent course generation & landing-page course previews (#663)

New features: - HLS video encoding/streaming (hls routes, hls-encoder) and a media transcripts pipeline (transcripts route + media-transcript queries) - AI assistant chat vs. run model: agent-course-generation worker/queue, run-monitor pane, chat-changes card, content ask-ai bar - Per-theme course-page previews across org landing-page themes (bold, classic, corporate, editorial, etc.) with a shared course token/component set - View-as-student mode and login-link / link-invite invite flows Refactor: - Extract packages/core consolidating config (env, storage, dashboard-url), services and utils previously duplicated under apps/api/src/config - Remove legacy agent service modules (chat-tools, chat-context, context-window, document, fetch-url, lesson-content) - Relax Cross-Origin-Resource-Policy to allow cross-origin media embedding - Add format script to tenant-router so turbo run format covers it
