fix(cli): fix flaky TestExpAgentsE2E/ExistingChatHistory (#24661)

- Remove racy sequential `expect("esc")` after `expect("direct open
seed")`
- Both strings appear in the same initial PTY render; their byte-stream
order depends on async title generation timing
- The seed text alone proves we are in the chat view; pressing esc +
expecting `enter: open` confirms list navigation
