As a user, I want to see the "Test Run Count" as a column in Test Execution List report

Description: 
As a user, I want to see the Test Run Count as a column in the Test Execution List report so that I can quickly understand the execution volume associated with each Test Execution without opening individual records.
 
User friction: 
Users must open each Test Execution or run additional queries/reports to determine how many test runs are included, making reporting and prioritization time-consuming.
 
Steps to reproduce (right now) / Actual Result: 
Actual Result:

The report does not display a Test Run Count column. Users must navigate into each Test Execution or create separate reports to determine the count.
 
IMPACT: Reduces efficiency for test managers, QA leads, and stakeholders who rely on list reports for monitoring execution progress, workload distribution, and execution coverage.

What would improve if solved: 

Faster assessment of execution size and complexity.

Current workaround: 
Users manually open each Test Execution to view its test runs, export data and calculate counts externally, or build custom JQL/reports if supported by their environment.
