Subject: [PATCH] chore(compliance): drop opencode zen free-pool from default
 config and docs
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

opencode.ai/zen is a free-quota pool for the official opencode app, keyed by
User-Agent fingerprint. Auto-provisioning it in the default config effectively
impersonated the official client to bypass FreeUsageLimitError — a ToS risk.
- default config (Go + GUI embed) now ships NO sources; users add their own
- README/README_EN: remove opencode adapter from built-in list and the zen
  free-pool paragraph
- adapter script and its unit tests stay (explicit opt-in only)

-zen 按 User-Agent 指纹识别官方客户端并分流——非官方 UA 的请求（curl、Go 默认 UA）
-会被丢进匿名池触发 `FreeUsageLimitError`。该适配器固定发送 opencode 客户端 UA，
-配合 `api_key: "public"`（官方无 key 客户端实际发送 `Bearer public`）即可走免费池，
-零成本接入 `deepseek-v4-flash-free` 等免费模型。

 **kimicode** 是展示 `build_headers` 的样例：云端校验调用方 app，需要按
 `meta.app_secret` 对时间戳+URL+请求体哈希做 HMAC 签名并附 `X-App-Sign` 等头。
 配好 `sources[].meta.{app_id, app_secret, app_agent}` 即可。
