IPTables-Management/install.sh
ahdoawhfo 26fbcf3584 Mark runnable scripts executable in git
The repo was committed from WSL with core.filemode=false, so the exec
bit was never recorded. After actions/checkout the entry script comes
down as 100644 and tests/test_cli.sh fails with Permission denied.

Set mode 100755 on every script that is invoked directly (entry,
installer, test suite, mock binaries). Sourced helpers under lib/
keep 100644 per convention.

用法:
sudo ./install.sh
sudo ./install.sh --uninstall
说明:
- 仅创建符号链接,不复制源码。
- 默认链接到 /usr/local/bin/iptables-forward。
- 可通过 INSTALL_TARGET 自定义目标路径。
