Derive a deterministic secp256k1 EOA from the passkey's PRF output via
HKDF-SHA256, enabling hardware-backed signing for x402 micropayments and
Safe treasury proposals without storing private keys.
Key changes:
- EOA key derivation with domain-separated HKDF (eoa-derivation.ts)
- Key manager integration with PRF-only EOA path (key-derivation.ts)
- Encrypted client-side wallet store for Safe associations (wallet-store.ts)
- Passkey-backed x402 signer replacing EVM_PRIVATE_KEY (passkey-signer.ts)
- Safe propose/confirm/execute proxy routes in rwallet (mod.ts)
- Wallet capability flag in JWT via users.wallet_address (server.ts)
- Payment operation permissions: x402, safe-propose, safe-execute (session.ts)
Privacy: Safe wallet associations stored client-side only (AES-256-GCM
encrypted localStorage). Server only knows user has wallet capability.
108 tests passing across 5 test suites.

Part of the ridentity.online branding migration. The EncryptID auth
server is now accessible at auth.ridentity.online (with the legacy
encryptid.jeffemmett.com kept as a backward-compatible alias).

Implements the EncryptID identity system for the r-ecosystem:
- WebAuthn/Passkey authentication with PRF extension for key derivation
- Client-side cryptographic key derivation (AES-256, ECDSA P-256, Ed25519)
- Social recovery system with guardians (no seed phrases!)
- Session management with authentication levels
- Cross-app SSO via Related Origin Requests
- Web components: login button and guardian setup panel
- Hono server for authentication endpoints
- Docker deployment configuration
