feat: support path parameters in tools and improve execution strategies

[swittlich]

This PR introduces support for Path Parameters within the Tool Engine. This allows for more robust handling of file system paths when invoking external tools, ensuring platform-specific path resolution and validation.

Key Changes

• Tool Engine Enhancements: Added support for path-based parameters in tool configurations.
• ToolCommandBuilder: Refactored the command builder to handle path resolution dynamically.
• Execution Strategy: Implemented a fallback mechanism to NativeStrategy for tool execution.
• Interfaces: Expanded IProject and tool-related interfaces (e.g., adding StartWeakProcess) to support the new workflow.

Technical Details

• Fixed platform-specific test failures in the ToolEngine that occurred during CI.
• Cleaned up the ToolCommandBuilder architecture to separate argument parsing from path resolution.

Testing

• Added a new suite of unit tests for ToolCommandBuilder.
• Verified path resolution across different OS environments (Linux/Windows).
