Release version 0.13.1

• fix(transport): Web mode no longer hangs on the "Connecting…" state when an ACP agent initializes before the WebSocket subscription is ready.
• fix(transport): mid-session WebSocket reconnects now restore ACP state automatically, so open conversations keep running without a manual reload.
• fix(acp): switching the agent or session at the same workspace tab no longer lets a stale snapshot overwrite the new connection's state.
• fix(transport): closing or switching a remote workspace fully releases its WebSocket, avoiding zombie reconnects and unexpected login redirects.
• fix(install): the install scripts now remove shadowing codeg-server binaries by default (--no-cleanup to opt out) and exit non-zero when the new install isn't what runs.
• fix(install): the Windows installer also cleans shadows on first install when its destination is freshly appended to PATH.

发布版本 0.13.1

• 修复(传输)：当 ACP 代理在 WebSocket 订阅完成前就初始化完成时，Web 端不再卡在「正在连接」。
• 修复(传输)：会话进行中 WebSocket 重连后会自动恢复 ACP 状态，无需手动刷新即可继续。
• 修复(ACP)：同一工作区标签内切换代理或会话时，旧连接的过期快照不再覆盖新连接的状态。
• 修复(传输)：关闭或切换远端工作区时彻底释放对应的 WebSocket，避免僵尸重连和意外的登录跳转。
• 修复(安装)：安装脚本默认会清理排在新安装之前的旧 codeg-server 二进制（--no-cleanup 可关闭），新安装未生效时返回非零退出码。
• 修复(安装)：Windows 安装脚本在首次安装将目标目录追加到 PATH 时也会清理影子二进制。
