v0.2.1

0.2.1 - Subscription-Backed Model Fallback

• Adds opt-in judged synthesis through existing subscription CLIs, starting with direct Claude and
  Gemini providers.
• Adds model fallback controls for surface audit, including --model-fallback,
  --model-channel, --model-channels, --model-depth, and --model-screenshots.
• Adds explicit egress policy, redacted model artifact persistence, cleanup support, and audit
  output disclosures for attempted, completed, unavailable, and blocked model channels.
• Adds a compatible MMR audit fallback boundary that reports unsupported capability without sending
  captured artifacts.
• Adds release and smoke coverage for subscription-backed model discovery while keeping default
  audits measured-only.
