NpmBasedCommandlet shows wrong tool version after install

[AdemZarrouki]

Actual behavior

After installing an NpmBasedCommandlet tool (e.g., Nest CLI), IDEasy’s output shows the current Node.js version as if it were the tool’s version (Nest), and it claims it “overwrote” a previous Nest version even though it did not. This is only a logging issue as the installation itself works correctly.

Reproduce

ide install nest

Expected behavior

After installing an NpmBasedCommandlet tool (e.g., Nest CLI), IDEasy should:

• Display the actual tool version that was installed (i.e., the npm package version such as @nestjs/cli’s version), not the current Node.js version.
• Only report “overwritten/updated” if a previous installation of that same tool existed and was actually replaced.
