Add live voice transcript, keyboard shortcuts, agent topology map

#3 Live Voice Transcript: Real-time subtitle bar at bottom of screen shows
what JARVIS hears as you speak. Interim results appear word-by-word via
SpeechRecognition.onresult interim events; bar fades 3.2s after final result.

#4 Keyboard Shortcuts: Global keydown handler (skips input fields):
F5=refresh all, Esc=close modals/overlays, M=mute mic toggle,
Space=focus chat input, 1/2/3/4=switch HOME/ALERTS/NEWS/AGENTS tabs.
Shortcut hints added to Ctrl+K palette footer.

#5 Agent Topology Map: TOPOLOGY button in AGENTS tab switches from card
view to animated ring-based canvas showing all agents by type (Proxmox=green
inner ring, HA=yellow mid ring, Linux/Windows=blue outer ring). Live particles
flow hub→agents; offline nodes shown in red. Reads from rendered agent cards.
