The 'should receive container stdout on attach' test was intermittently failing because it didn't wait for stream data to be fully written before asserting. After containerWait() completes, explicitly wait for the stdout stream to finish by calling stream.end() and listening for the 'finish' event. This ensures all piped data has been written to the stdoutData array before assertions. Signed-off-by: MattHandzel <handzelmatthew@gmail.com>

- What I did
Fixes #31 "investigate flaky test"
- How I did it
Explicitly waiting for stdout stream to finish by calling stream.end() and listening for the 'finish' event. This ensures all piped data has been written to the stdoutData array before any test assertions, which fixes flaky behavior.
- How to verify it
Run
npm test -- --run "test/container.test.ts" -t "should receive container stdout on attach"until you are convinced it is no longer flaky. (I ran it 200 times)- Human readable description for the release notes
