- Add src/lib/sessionCrypto.ts with AES-GCM-256 non-exportable session keys - Integrate into Backup flow: auto-clear plaintext mnemonic after QR generation - Add Lock/Clear button to destroy session key and clear all state - Add cleanup useEffect on component unmount - Add comprehensive GEMINI.md for AI agent onboarding - Fix TypeScript strict mode errors and unused imports Tested: - Session-key encryption working (mnemonic clears after QR gen) - Lock/Clear functionality verified - No plaintext secrets in localStorage/sessionStorage - Production build successful
