feat(autoware_trajectory_follower_node): adopt cie

[TetsuKawa]

Description

Apply autoware_agnocast_wrapper to enable CallbackIsolatedAgnocastExecutor (CIE) for this package, as part of the effort to achieve middleware-transparent scheduling and optimize end-to-end response time across Autoware. By going through autoware_agnocast_wrapper, CIE activation is controlled by the ENABLE_AGNOCAST environment variable — when unset or 0, the node runs with the standard ROS 2 executor as before; when set to 1, it switches to CallbackIsolatedAgnocastExecutor.

Changes

• CMakeLists.txt: Replaced rclcpp_components_register_node with autoware_agnocast_wrapper_register_node, adding ROS2_EXECUTOR SingleThreadedExecutor and AGNOCAST_EXECUTOR CallbackIsolatedAgnocastExecutor options.
• package.xml: Added autoware_agnocast_wrapper.

Notes for reviewers

Please review the following aspects:

• Verify that all relevant CMakeLists.txt and launch files in this package have been updated (no missed files).
• If the node meets all of the following conditions, please check for potential race conditions (see Effects on system behavior for the reason):
  1. The node was originally running on a SingleThreadedExecutor
  2. The node has multiple callback groups
  3. Shared variables are accessed across callback groups without proper mutex protection

Interface changes

None.

Effects on system behavior

When ENABLE_AGNOCAST=0 (default), there is no change in behavior at all — the node runs with the standard ROS 2 executor exactly as before.

When ENABLE_AGNOCAST=1, the executor switches to CallbackIsolatedAgnocastExecutor (CIE). Internally, CIE creates a dedicated rclcpp::SingleThreadedExecutor for each callback group, so the fundamental scheduling behavior within each group remains almost identical. The key difference is that, for nodes originally using SingleThreadedExecutor, callback groups now run in parallel across separate threads, similar to MultiThreadedExecutor.

Pull request overview

Adopts autoware_agnocast_wrapper in autoware_trajectory_follower_node so the node can switch between the standard ROS 2 executor and CallbackIsolatedAgnocastExecutor (CIE) via ENABLE_AGNOCAST.

Changes:

• Register both component nodes via autoware_agnocast_wrapper_register_node with explicit ROS 2 and Agnocast executor types.
• Add autoware_agnocast_wrapper build configuration and dependency wiring (CMake + package.xml).

Pull request overview

This PR adopts autoware_agnocast_wrapper in autoware_trajectory_follower_node so the node can switch between the default ROS 2 executor and CallbackIsolatedAgnocastExecutor based on the ENABLE_AGNOCAST environment variable.

Changes:

• Add autoware_agnocast_wrapper as a package dependency.
• Update component registration in CMakeLists.txt to use autoware_agnocast_wrapper_* macros and configure ROS2/agnocast executors.
