This PR removes an unnecessary intermediate collection step when extending entry points with dynamic import entry IDs, improving performance by eliminating an extra allocation.

  • Removes redundant .collect::<Vec<_>>() call that immediately preceded .into_iter()
  • Removes outdated comment referencing inline_dynamic_imports which doesn't exist in the codebase
