feat: fix RAG pipelines, Beep Graph branding, PWA, and ambient glow UI

Pipeline fixes:
- Fix agent getting empty response from graph-rag by combining answer +
  explain data in single message (RequestResponse returns first msg)
- Fix Doc RAG pipeline: add content field to Qdrant doc payload, seed 10
  document chunks, fix type mismatches across base/flow/client
- Forward explainability events from agent's KnowledgeQuery to client
- Add "agent" to TERM_BEARING_RESPONSE_SERVICES for triple translation
- Fix embeddings env var (OLLAMA_URL), user/collection threading, edge
  scoring threshold, and various protocol mismatches

Branding:
- Rename TrustGraph → Beep Graph (title, sidebar, settings, about)
- Custom lambda + ThugLife pixel glasses SVG logo component
- Forest green color palette (brand-50 through brand-900)
- SVG favicon + PNG icons (16/32/180/192/512)
- PWA manifest with service worker for offline shell caching
- Splash screen with animated logo pulse on app load
- Ambient glow background with drifting green radial blobs
