Implements LNURL address caching similar to NIP-05 caching pattern: **Database Changes** (v16): - Add `lnurlCache` table with 24-hour TTL - Stores LNURL-pay response data for Lightning addresses - Indexed by address and fetchedAt for efficient queries **New Hook** (`useLnurlCache`): - Reactive hook using Dexie + useLiveQuery pattern - Auto-fetches and caches LNURL data on first use - Returns cached data instantly on subsequent calls - Re-fetches when cache is stale (>24 hours) **ZapWindow Optimization**: - Uses cached LNURL data instead of network calls - Eliminates 10-second delay on repeat zaps - Shows zap amounts/limits instantly from cache - Graceful error handling when cache is warming up **Testing**: - 11 comprehensive tests for LNURL validation - Validates zap support, pubkey format, field requirements - Tests edge cases (uppercase hex, missing fields, etc.) **Benefits**: - Instant zap UI for frequently zapped users - Reduced load on LNURL servers - Offline capability (show cached limits/amounts) - Better UX with sub-100ms response time Verification: All 950 tests pass, build succeeds
