1518 uv tools are now installed locally

[ducminh02]

This PR fixes #1518

Implemented changes:

• Full Project Isolation: Redirected uv tool data and virtual environments to the project-local software/python/tools directory via UV_TOOL_DIR.

• Explicit Binary Pathing: Replaced XDG_BIN_HOME with UV_TOOL_BIN_DIR to ensure tool executables are scoped to the project's bin folder.

• Commandlet Updates: Modified Python.java and Uv.java to export these variables automatically, eliminating all "not on your PATH" warnings.

• Regression Testing: Added cross-platform JUnit tests to verify environment isolation across both tools.

I just tested your PR. Generally, it seems to work very well. uv tools are now always installed within the IDEasy project.

However, I noticed the following: uv tools that are installed within an IDEasy project are also available in all other projects. For example, if I install the tool "ruff" in the IDEasy project "A", then the tool is installed correctly under $IDE_ROOT/A/software/python/bin/ruff . But if I then switch to IDEasy project B and execute uv tools list, then the ruff tool is still available. The tool cannot be reinstalled in project B either, because it is already installed in project A. Furthermore, uninstalling (or deleting) the tool will then lead to it no longer being available in any of the projects.

The goal was that uv should be installed in an isolated way. This is also achieved for the uv installation itself. However, the fact that uv tools are then shared across projects violates this goal somewhat IMO. Can you take a look at it again?

I have made the adjustments to enable uv to install tools in a isolated way, can you have a look at it to see if it works now?
