fix(tests): align broken test assertions with current behavior (#1791)

* fix(tests): align broken test assertions with current behavior

- test_readme_native_quickstart_uses_loopback: README warning text
  moved from --host prefix to bind-to phrasing; update assertion
- test_sanitize_merges_consecutive_user_messages: consecutive user
  messages ARE merged and orphan tool messages ARE dropped by the
  adjacency repair pass; update expected counts and values

* fix(tests): update cookbook status poll assertion for stopped state

The cookbookRunning.js ternary now handles a 'stopped' status
alongside 'error', so the exact string match in the test no longer
holds. Relax the assertion to check for the error branch presence
instead of the full ternary expression.
