chore: add critical orchestration test coverage

[GangGreenTemperTatum]

Adds targeted test coverage for the highest-risk untested runtime paths.

What changed

• Added robust unit tests for Loader.run() orchestration, including argument/volume mapping, artifact handling, profile parsing, stdout merging, timeout behavior, and container error handling.
• Added Tracer.run_trace() coverage for lifecycle orchestration, tracer error propagation, and containerId event filtering.
• Added CLI coverage for missing policy validation, non-Linux GPU auto-disable behavior, and verbose exception re-raise behavior.

Why
The existing suite was strong on helpers and formatting, but weak on the Docker/Tracee execution paths most likely to fail in production while tests still stayed green.

Verification

• pytest dyana -q

---

Generated Summary:

• Added tests for the CLI trace command to enhance error handling:

  • Verifies that the command rejects a missing policy file with an appropriate error message.
  • Confirms that GPU is disabled on non-Linux systems during a trace operation.
  • Assures that verbose mode correctly raises exceptions.

• Introduced a new test class to cover loader run executions:

  • Added functionality to parse profile and merge extra stdout during loader runs.
  • Implemented a test for the run method timing out and correctly killing the container.
  • Verified that the run method handles container execution errors appropriately.

• Expanded testing coverage for the Tracer class:

  • Added a test to filter tracer events and merge errors from both the tracer and loader.

• Overall, these changes improve test coverage and robustness in error handling for the CLI and loader functionalities.
