/**
 * Low-level HTTP transport for the TencentDB Agent Memory v2 API.

 * - Auth: `Authorization: Bearer {apiKey}` + `x-tdai-service-id` + optional `x-tdai-user-key`
 * - Envelope unwrap: `code === 0` → return `data`; else throw `TDAMError`
 * - trace_id: extracted from `x-trace-id` response header
 * - Zero runtime dependencies — uses native `fetch`.
 * - TLS: `rejectUnauthorized` defaults to `false` (self-signed cert friendly).
