fix(test): Make TerminalProcess integration test reliable

This commit fixes the flaky test case `integrates with getUnretrievedOutput to handle progress bars` in `TerminalProcess.test.ts`.

The test previously failed intermittently due to:
1.  Relying on a fixed `setTimeout` duration to wait for asynchronous stream processing, which created a race condition.
2.  Incorrectly assuming that `await terminalProcess.run(...)` would return the final output directly via its resolved value.

The fix addresses these issues by:
-   Removing the unreliable intermediate check based on `setTimeout`.
-   Modifying the test to correctly obtain the final output by listening for the `completed` event emitted by `TerminalProcess`, which is the intended way to receive the result.

This ensures the test accurately reflects the behavior of `TerminalProcess` and is no longer prone to timing-related failures.
