# deploy-local-brew.sh — 方案 2：本地构建 → 通过 brew 安装到 /opt/homebrew/bin，零 CI。
#
# 用途：本机快速调试 patch 级改动。**产物仅在本机**，不上传 GitHub，公共 tap 不变。
# 与 deploy-local-mac.sh 的区别：不再把二进制裸拷到 ~/.local/bin，而是经 brew 管理
# （/opt/homebrew/bin），因此 launchd / brew services 指向的 brew 路径会拿到新二进制。
#
# 流程：
#   1. 本地 cargo build --release（host arch）出 ilink-hub + ilink-hub-bridge
#   2. ad-hoc 重签（避免 macOS AMFI 运行时 SIGKILL / "killed: 9"）
#   3. 临时把 jeffkit/tap 的 formula 改成 file:// 指向本地产物 + 本地 sha256
#   4. brew reinstall（从本地文件装到 Cellar，并 relink /opt/homebrew/bin）
#   5. 还原 tap formula（git checkout），保持 tap 干净
#
# 用法：
#   scripts/deploy-local-brew.sh                          # 用 Cargo.toml 的版本，默认重载 launchd
#   ILINK_NO_RELOAD_LAUNCHD=1 scripts/deploy-local-brew.sh  # 跳过重载（仅换二进制，不动服务）
#
# 注意：这是「本机调试」路径。要让其它机器 / 公共 tap 拿到新版本，请用方案 1
# （打 v*-mac tag 触发 release-mac-fast.yml）或完整 release（打 vX.Y.Z tag）。
