fix(tests): Remove temp files created in aiperf unit-tests

[tgasser-nv]

Summary

In unit-tests, the AIPerfConfig output_base_dir was set to test_output in the pytest feature create_config_data(). In two tests, the config was used and created directories below the PWD. This fix changes each test to default output_base_dir to a temporary directory created by pytest using the tmp_path fixture.

Description

Before the change

$ poetry run pytest -q
$ ls -1 test_output/test_batch/20251211_190139  # Timestamp will match run time
concurrency1
concurrency2
process_result.json
run_metadata.json

After the change

$ poetry run pytest -q
$ ls -1 test_output
ls: test_output: No such file or directory

Greptile Summary

Fixed temporary file cleanup issue in AIPerf unit tests by switching from hardcoded "test_output" directory to pytest's tmp_path fixture, ensuring test artifacts are automatically cleaned up after test execution.

• Updated create_config_data fixture to accept and use tmp_path parameter
• Changed default output_base_dir from hardcoded string to str(tmp_path)
• Updated test assertion in test_init_with_valid_config to use str(config_file.parent) instead of hardcoded path
• Minor formatting fix in streamers.py (moved type ignore comment)

Confidence Score: 5/5

• This PR is safe to merge with minimal risk
• The changes are minimal and focused on test hygiene, using pytest's built-in tmp_path fixture which is the standard approach for temporary file handling in tests. All test assertions have been properly updated to reflect the new dynamic paths. No production code is affected except for a minor formatting change.
• No files require special attention
