fix: Prevent queue_test from overwriting completed test status

[cfsmp3]

Summary

Prevent queue_test() from posting "Tests queued" status when a test has already started or completed.

Problem

When multiple GitHub Actions workflows complete for the same commit (e.g., Linux build finishes first, then Windows build finishes later), the webhook handler calls queue_test() for ALL platforms each time. This caused completed tests to have their GitHub status overwritten.

Example from CCExtractor/ccextractor#1744 (stuck since September 2025):

Time (UTC)	State	Description
14:22:13	PENDING	Loaded variables...
14:22:20	PENDING	Running tests
14:52:59	SUCCESS	Not all tests completed successfully ✅
14:56:59	PENDING	Tests queued ❌ (overwrote SUCCESS!)

Also observed on CCExtractor/ccextractor#1916.

Solution

Check if the test already has progress entries before posting "Tests queued". If the test has started or completed, skip the GitHub status update.

if len(platform_test.progress) > 0:
    log.info(f"Test {platform_test.id} already has progress, not posting 'Tests queued' status")
    return

Test plan

• Manual code review
