/**
 * Cloudflare KV Delegation Verifier
 *
 * Stores delegations in Cloudflare Workers KV for high-performance,
 * edge-cached delegation verification.
 *
 * Performance:
 * - Fast path (cached): < 5ms
 * - Slow path (KV read): < 50ms
 * - Cache TTL: 1 minute (configurable)
 *
 * Key Structure:
 * - `delegation:{delegationId}` - Full delegation record
 * - `agent:{agentDid}:scopes:{hash}` - Delegation lookup by agent+scopes
 *
 * Related: PHASE_1_XMCP_I_SERVER.md Ticket 1.2
