chore(module): Go module 路径随托管地迁移 gitcode → github

## 背景

仓库早已迁移到 GitHub（`github.com/JianFeeeee/HomeAgent`，CI/CD 都在那边跑），
gitcode 保留为**国内只读镜像**（`ci.yml` 的 sync-gitcode-main 快进推送）。
但 go.mod 的 module 路径一直是 `gitcode.com/JianFeeeee/...` —— 既与权威源
不符，`meta.SourceURL`（AGPL §13 的源码提供入口）也指向镜像而非实际运行的代码。

## 关键区分（这是本次改动安全的前提）

两个 module 是**不同**的，影响面差一个数量级：

| module | 谁依赖 | 改它的后果 |
|---|---|---|
| `.../HomeAgent`（主仓） | **只有主仓自己** | 内部重构，零外部影响 |
| `.../homeagent-sdk`（SDK 仓） | 主仓 49 文件 + 所有外部插件 | 需重编插件 |

★ 实测确认：**插件不 import 主仓 module**（`strings qq/plugin.bin | grep HomeAgent` = 0），
只依赖 SDK 仓。而插件与内核的边界是 **RPC 方法名字符串**
（`plugin.init` / `tool.invoke`…，见 proc/protocol.go），**与 Go module 名无关**。
⇒ module 改名**不改变任何 wire 协议**，现网已装的插件照常运行。

SDK 的 GitHub 仓名是 `homeagentsdk`（无连字符），module 路径必须与之精确匹配，
否则 `go get` 会因路径不符失败，故取 `github.com/JianFeeeee/homeagentsdk`。

## 改动

- `go.mod` / `go.sum`：两个 module 路径 + require/replace
- 277 个 Go 文件 + Makefile + 打包脚本的 import 与 ldflags 路径
- SDK 仓 `meta.CoreModule`、`tools/hmapdev` 的 module 声明与工程模板
- 对外文档/链接的仓库地址（README、PLUGIN_DEV、OVERVIEW 等）

## 明确**保留** gitcode 的地方（镜像机制，不能动）

- `GITCODE_TOKEN`、`GC_URL="…@gitcode.com"`（CI 同步 job）
- `gitcode.com/api/v5/...`（release 附件上传）
- git remote `gitcode`（镜像拉取/推送）
- `docs/zh/ci-cd-runbook.md`（整篇讲镜像运维）

## 验证

- `go build ./...` / `go vet ./...` 绿
- `go test ./... -count=1` → 48 包 ok / 0 FAIL
- hmapdev 工具链编译通过（`third_party/homeagent-sdk/tools/hmapdev`）
- 全仓残留检查：module 形态的 `gitcode.com/JianFeeeee` = 0
- 镜像机制抽验：GC_URL / @gitcode / api/v5 / remote 均完好

## 顺带修正

`hmapdev/templates.go` 的注释此前写「gitcode 的模块不在 proxy.golang.org 上」——
module 已迁 GitHub，该论断不再成立。改为如实说明**为何仍默认 replace 到本机 SDK**：
离线可构建、避免版本漂移、内网可用。理由与托管地无关，故 replace 保留。
