Current evaluation

Placeholder tracking task for adding core26 (Ubuntu 26.04) support to the colcon plugin and ROS 2 extensions. Core26 base support and the ros2-lyrical extensions have since landed, but no colcon-specific core26 work or PR is referenced; issue remains unlabelled with zero comments.

Suggested action: needs triage

Reason: The issue is a maintainer-authored placeholder with no labels, assignee, or comments, so it has not been triaged. Related work has landed since it was filed — PR #6053 added the ros2-lyrical (core26) extensions and #6315 fixed the ros 2 extension for core26 — but the colcon plugin itself still has no core26-specific handling (its get_build_packages only special-cases core22), so the task is not fully complete and should be assessed rather than closed.
