Add nsys to PATH env

[mitul93]

Problem

When using nsys CLI for profiling, a .nsys-rep report is not generated successfully.

Instead, profiling produces only a .qdstrm file and reports an importer error.

Steps to Reproduce

$ nsys profile --trace=cuda --output=report ./test
...
Collecting data...
Generating '/tmp/nsys-devcontainer/nsys-report-f8d1.qdstrm'
Importer error status: An unknown error occurred.
Unable to retrieve the importer version: skipping importation of the QDSTRM file.
Generated:
        /current_working_dir/report.qdstrm

Environment

Item	Value
OS	Ubuntu
Feature	nsight-systems-cli
Feature Version	1.0.1
Nsight Systems Version	2026.3.1.157-263138048394v0

Expected Behavior

nsys profile should successfully generate a .nsys-rep report.

Actual Behavior

Only a .qdstrm file is generated, and the import step fails with the following error:

Importer error status: An unknown error occurred.
Unable to retrieve the importer version: skipping importation of the QDSTRM file.

Impact

The generated .qdstrm file cannot be directly consumed by most CLI workflows, requiring manual import in the Nsight Systems UI.

This also prevents post-processing with commands such as:

nsys stats report.nsys-rep

Proposed Fix

Ensure that QdstrmImporter is available on $PATH.

For example:

cd /opt/nvidia/nsight-systems-cli/2026.3.1/host-linux-x64
ls -l

The devcontainer feature should append this directory to the PATH environment variable so that nsys can invoke QdstrmImporter during report generation.
