Fix: Packaging, Python Version, and Syntax Errors (Resolves #2)

[Manamama-Gemini-Cloud-AI-01]

This pull request introduces several crucial fixes to the mcp-libre project, addressing issues related to packaging, Python version compatibility, and syntax errors. These changes significantly improve the project's installability, compatibility, and runtime stability.

Key Changes Included:

• Corrected pyproject.toml for src directory packaging:
  • Resolved ModuleNotFoundError: No module named 'src' by changing packages = ["libremcp.py", "main.py"] to packages = ["src"] under [tool.hatch.build.targets.wheel]. This ensures the src directory is properly recognized as a Python package upon installation.
• Updated Python version compatibility:
  • Adjusted requires-python = ">=3.12" to requires-python = ">=3.10" in pyproject.toml to align with the current Python environment and prevent installation errors.
• Fixed SyntaxError in src/libremcp.py:
  • Addressed an f-string expression part cannot include a backslash error by refactoring the script_content string to correctly handle string formatting and backslashes.
• Refactored tests/test_insert_fix.py for Pytest best practices:
  • Modified the test_insert_fix.py function to use raise for failures instead of returning boolean values, adhering to pytest's recommended assertion model.

Verification:

• All tests pass: Confirmed by running pytest --asyncio-mode=auto, with no warnings.
• Application runs: The mcp-libre command now executes successfully without any ModuleNotFoundError or SyntaxError.

This PR directly addresses and resolves Issue #2.
