fix(test): add missing pytest markers to video/audio protocol tests

[KrishnanPrash]

Overview

The video streaming PR (#8491) added 3 test files to components/src/ right after the marker enforcement PR (#7796) expanded the pre-commit check to that directory. Since the new tests didn't include the required markers, every PR's pre-commit hook started failing — 49 tests flagged as missing Lifecycle, Test Type, and Hardware markers.

This adds the standard pytestmark block to those 3 files so pre-commit passes again.

Repro:

python3 tests/report_pytest_markers.py
# Before: Missing sets: 49 (exit 1)
# After:  Missing sets: 0

Details

The marker enforcement hook (pytest-marker-report) requires every test to carry at least one marker from each of three categories: Lifecycle (pre_merge, post_merge, etc.), Test Type (unit, integration, etc.), and Hardware (gpu_0, gpu_1, etc.).

The video streaming PR landed ~40 minutes after the enforcement expansion, and its tests didn't have any markers. Since the hook scans all files (not just changed ones), this broke pre-commit for every subsequent PR.

Files fixed:

• components/src/dynamo/common/tests/test_audio_protocol.py
• components/src/dynamo/common/tests/test_video_protocol.py
• components/src/dynamo/common/tests/test_video_utils.py

All three are pure pydantic/protocol validation tests — no GPU, no external services — so unit, gpu_0, pre_merge is the right fit, matching adjacent files in the same directory.

Where should the reviewer start?

Any of the 3 files — the change is identical in each: a pytestmark list after the imports.

Test Plan

• Ran python3 tests/report_pytest_markers.py on main → Missing sets: 49
• Ran same after fix → Missing sets: 0
• Checked the enforcement commit (before video streaming landed): Missing sets: 0 — confirms the video streaming PR is the source
• Checked the video streaming commit: Missing sets: 49 — confirms root cause

Summary by CodeRabbit

• Tests
  • Added global test markers to three test modules (audio protocol, video protocol, and video utilities tests)
  • Tests now tagged with unit, gpu_0, and pre_merge classification

Walkthrough

Three test modules in the dynamo/common/tests directory now declare a module-level pytestmark variable with unit, gpu_0, and pre_merge markers. This ensures all tests within these modules inherit these markers during test collection and execution. No test logic or assertions were modified.

Changes

Cohort / File(s)	Summary
Pytest markers configuration components/src/dynamo/common/tests/test_audio_protocol.py, components/src/dynamo/common/tests/test_video_protocol.py, components/src/dynamo/common/tests/test_video_utils.py	Added module-level pytestmark variable with three pytest markers (unit, gpu_0, pre_merge) to apply globally to all tests in each module. No test logic changes.
