/**
 * Builds the deterministic `a` tag value for a URL-based zap.
 * Format: "39735:<recipient_pubkey>:<normalized_url>"
 * Kind 39735 is in the NIP-01 addressable event range (30000-39999), making
 * this a valid event coordinate that NIP-57 relays copy from the zap request
 * to the zap receipt, enabling relay-side #a filtering.
 *
 * Note: kind 39735 is also referenced by the publsp project for Lightning LSP
 * liquidity offers. No actual kind 39735 event is ever published here — the
 * number is used purely as a stable coordinate prefix. The d-field is always a
 * normalized URL, which is semantically distinct from publsp identifiers, so
 * the overlap is benign in practice.
