/**
 * Pacifica agent-wallet signing builders (Phase 2c).
 *
 * Pacifica auth model — off-chain signed messages over Solana Ed25519.
 * Reference: https://pacifica.gitbook.io/docs/api-documentation/api/signing.md
 *
 * Canonical JSON rules (from Pacifica signing spec + production reference
 * `src/pacifica/signing.ts:prepareMessage()`):
 *   1. Recursively sort all object keys alphabetically.
 *   2. Compact JSON (`JSON.stringify(value)` — no whitespace).
 *   3. Outer wrapper has the shape `{ <header fields>, "data": <payload> }`
 *      where header is `{ type, timestamp, expiry_window }`. The `data` key
 *      is sorted lexicographically alongside the header fields.
 *
 * The agent bind/unbind action types are documented in HypurrQuant_FE
 * `PacificaPerpAdapter.ts` (production reference for HypurrQuant_FE; see
 * project memory `hypurrquant_fe_reference.md`). We mirror their `bind_agent_wallet`
 * and `unbind_agent_wallet` operation types here.
 *
 * Pure functions — no side effects, no fs/fetch/env reads.
