Which components does the task require to be changed? (think hard pls)

Description

Currently the --coverage flag always creates and overwrites the coverage.lcov file. Consider either making the output file configurable or including a timestamp/hash of trace data files (or something similar) in the output file name. Refer to the initial discussion #2369 (comment)

Imo timestamp is better tbh it is a standard for such files, hash seems like massive overcomplication.
