fix: validate Python module syntax during module_manager install

[HaibinLai]

module_manager install previously accepted Python modules with syntax errors (e.g. IndentationError) without any validation. The error was only discovered at runtime when the BMF graph attempted to load the module, causing a crash.

This PR adds a py_compile syntax check in the install_module() function for Python modules. If the syntax check fails, the installation is aborted with a error message showing the syntax error and line number.

relate issue: #193

How to Reproduce

1. Create a Python module with a syntax error:

2. Install the module

BMF_BIN="/home/xxx/se_pr/bmf/build/output/bmf/bin/module_manager"
BMF_LIB="/home/xxx/se_pr/bmf/build/output/bmf/lib"

sudo LD_LIBRARY_PATH="${BMF_LIB}" \
    ${BMF_BIN} install my_python_module python my_module:my_module \
    $(pwd)/my_python_module v0.0.1

Before this fix, the installation reports success even though the module contains invalid Python syntax.

After this fix, the installation fails early with a clear error message:
