feat(cli): run end-to-end tests in parallel

[saeta-eth]

Closes https://linear.app/usecannon/issue/CAN-492/run-cli-e2e-in-parallel

This PR introduces parallelized end-to-end testing, allowing nearly half of the CLI tests to run concurrently. However, some tests depend on the execution of other commands and must be run sequentially instead of in parallel
