初始提交：terminalX 可运行态（M0/M1/M1.5 已真机验证）

- M0: libghostty SSH 终端（渲染/输入/连接）+ 白屏修复(OutputGate) + 会话状态机/自动重连
- M1: tsnet 用户态组网 + SSH-over-tsnet(fd 桥)，shell 级真机验证；R5(Go+gvisor+C+++Swift 同进程) retire
- M1.5: tmux -CC 原生 tab（MVP）
- 结构: packages/(TXCore·TXTransport), apps/TerminalX, vendor/(libghostty-spm/libssh2/mbedtls/tsnet-bridge), artifacts/
- 文档: CLAUDE.md + docs/HANDOFF.md（新会话入口）
- 环境: 认证代理→依赖 vendor 本地化；Go 在 ~/.local/go；仅模拟器/未签名
- 待续: M2 mosh, tmux 多 pane, M4 安全(host key/SE)

+README for git hooks script
+===========================
+git has a way to run scripts, which are invoked by specific git commands.
+The git hooks are located in `<Mbed TLS root>/.git/hooks`, and as such are not under version control
+for more information, see the [git documentation](https://git-scm.com/docs/githooks).
+
+The Mbed TLS git hooks are located in `<Mbed TLS root>/tests/git-scripts` directory, and one must create a soft link from `<Mbed TLS root>/.git/hooks` to `<Mbed TLS root>/tests/git-scripts`, in order to make the hook scripts successfully work.
+
+Example:
+
+Execute the following command to create a link on Linux from the Mbed TLS `.git/hooks` directory:  
+`ln -s ../../tests/git-scripts/pre-push.sh pre-push`
+
+**Note: Currently the Mbed TLS git hooks work only on a GNU platform. If using a non-GNU platform, don't enable these hooks!**
+
+These scripts can also be used independently.

+#
+# Purpose
+#
+# Called by "git push" after it has checked the remote status, but before anything has been
+# pushed.  If this script exits with a non-zero status nothing will be pushed.
+# This script can also be used independently, not using git.
+#
+# This hook is called with the following parameters:
+#
+# $1 -- Name of the remote to which the push is being done
+# $2 -- URL to which the push is being done
+#
+# If pushing without using a named remote those arguments will be equal.
+#
+# Information about the commits which are being pushed is supplied as lines to
+# the standard input in the form:
+#
+#   <local ref> <local sha1> <remote ref> <remote sha1>
