BA Click 0.2.0

• 2026-08-22

Added / 新增

• Right/middle-click effects: right-click (button 2) and middle-click (button 3) now trigger the click effect too; the panel gains independent toggles. Trail also follows right/middle drags.
  右键 & 中键点击效果：右键、中键同样触发点击特效，面板可独立开关；按住右/中键拖动也会出现尾迹。
• Update check + self-update: panel's 检查更新 queries GitHub Releases; one-click auto-update (download matching-arch DMG → mount → replace → relaunch), falls back to the Releases page when auto-update isn't possible.
  检查更新 + 自动更新：查询 GitHub 最新版本，一键自动更新（下载 DMG → 挂载 → 替换 → 自动重启）；无法自动更新时跳转 Releases 页面手动下载。
• GitHub repo button next to the update check.
  「GitHub 仓库」按钮与「检查更新」同一行。
• GitHub proxy fallback for the update check and DMG download (gh-proxy.org → gh-proxy.com → ghproxy.net → ghfast.top) when the direct connection fails.
  GitHub 代理回退：直连失败时按序走代理完成检查更新与 DMG 下载。

Fixed / 修复

• run.sh now rebuilds when sources change (was running a stale binary).
  run.sh 源码变更后会自动重新构建（此前运行旧二进制）。

Engineering / 工程

• Fixed build.sh --release crashing on an empty signing-args array under bash 3.2 set -u.
  修复 build.sh --release 空签名参数数组在 bash 3.2 set -u 下的崩溃，发布管线恢复可用。
