d021e21544 feat: server-side PPTX conversion + screenshot dashboard system 
PPTX Conversion:
- Remove LibreOffice from client dependencies (server uses Gotenberg)
- Update docs to reflect clients only display pre-rendered PDFs
- Clarify server-side conversion workflow in README and copilot-instructions

Screenshot System:
- Add background screenshot capture in display_manager.py
- Implement Wayland/X11 session detection with tool fallback
- Add client-side image processing (downscale + JPEG compression)
- Create timestamped files + latest.jpg symlink for easy access
- Implement file rotation (max 20 screenshots by default)
- Enhance simclient.py to transmit via MQTT dashboard topic
- Add structured JSON payload with screenshot, timestamp, system info
- New env vars: SCREENSHOT_CAPTURE_INTERVAL, SCREENSHOT_MAX_WIDTH,
  SCREENSHOT_JPEG_QUALITY, SCREENSHOT_MAX_FILES, SCREENSHOT_ALWAYS

Architecture: Two-process design with shared screenshots/ volume

65d7b99198 Improve MQTT resilience, clarify behavior, and minor UX 
Switch to Paho v2 callbacks; add loop_start() and reconnect_delay_set() for auto-reconnect
Rework on_connect/on_disconnect to v2 signatures; handle session_present and reconnection flows
Gate heartbeats with client.is_connected() and add short retry on rc=4 (NO_CONN)
Re-send discovery after reconnect; ensure re-subscription to all topics
Add startup terminal message with ISO timestamp in simclient.py
Docs: update README and Copilot instructions with reconnection/heartbeat guidance and benign rc=4 notes
