Deprecate 'slient' param in get_blocks_()

[IvanaGyro]

"slient" argument was corrected to "silent" in #666. However, that change broke the current Python API. This PR adds "slient" back and marks it deprecated until v2.0.0.

• Restore 'slient' parameter support to fix API breaking change from previous commit
• Add FutureWarning for deprecated 'slient' parameter using py::warnings
• Implement robust argument validation with detailed error messages
• Bump pybind11 requirement to >=3.0 (py::warnings available since pybind11 3.0)
• Add comprehensive test suite covering deprecation warnings, argument validation, and edge cases

How about:

// Helper function to parse the 'silent' argument for get_blocks_() method                                                                                                                                  
// This function handles backward compatibility with the deprecated 'slient' parameter
static inline bool check_silent(py::args args, py::kwargs kwargs) { 
    // ...
}

.def("get_blocks_", [](const UniTensor& self, py::args args, py::kwargs kwargs) {
    return self.get_blocks_(check_silent(...));
}
.def("get_blocks_", [](UniTensor& self, py::args args, py::kwargs kwargs) {
    return self.get_blocks_(check_silent(...));
}

Extracted the function.
