test: Update version assertions to 2.5.0

Updated test expectations from old versions to 2.5.0:
- tests/test_package_structure.py: 4 assertions (cli, mcp, mcp.tools, root)
- tests/test_cli_paths.py: CLI version output
- tests/test_adaptors/test_base.py: Metadata test data

All tests now expect 2.5.0 instead of 2.0.0/2.4.0.
