Noru Flow v0.1.0

First signed and notarized macOS build.

• Instant capture bar: fullscreen, region, and video capture without leaving the keyboard.
• Agent handoff over MCP: a local read-only server exposes recent captures to a CLI agent.
• On-device audio: microphone health facts on every recording, and a Premium on-device
  speech transcript fused into the capture timeline. Audio stays on your Mac.
• Auto-update: signed delta updates over the in-app updater.
