Greptile Summary

This PR bumps the pinned ros-dev container digest to a new image version and makes the ROS environment-sourcing step in CI adaptive by replacing the hardcoded humble distro name with the $ROS_DISTRO environment variable (which the ROS container already exports).

• docker/ros-dev-pin/Dockerfile: Updates the @sha256: digest to point to the new ros-dev image; the :latest tag is preserved so Dependabot can continue tracking updates.
• .github/workflows/ci.yml: Replaces /opt/ros/humble/setup.bash with /opt/ros/${ROS_DISTRO}/setup.bash, making the sourcing step work correctly regardless of which ROS distro the container ships.

Confidence Score: 5/5

Safe to merge — both changes are narrow, well-scoped, and consistent with the existing workflow design.

The digest bump is a routine image update, and replacing the hardcoded humble distro with $ROS_DISTRO correctly adapts to whatever distro the new image ships. The $ROS_DISTRO variable is already relied upon by the surrounding step (it is echoed into GITHUB_ENV), so it is guaranteed to be present in the container environment. The step is also gated to Linux-only runners, keeping macOS paths unaffected.

No files require special attention.

Important Files Changed

Filename	Overview
docker/ros-dev-pin/Dockerfile	Routine digest bump to the new ros-dev image; structure and comments unchanged.
.github/workflows/ci.yml	Makes the ROS setup path use $ROS_DISTRO instead of hardcoded "humble"; $ROS_DISTRO is already expected by the surrounding step logic.
