feat(shape_estimation): use CallbackIsolatedAgnocastExecutor for shape_estimation

[Koichi98]

Description

Use AgnocastOnlyCallbackIsolatedExecutor (CIE) for shape_estimation node, 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 AgnocastOnlyCallbackIsolatedExecutor.

Changes

• CMakeLists.txt: Set SingleThreadedExecutor explicitly for ROS_EXECUTOR and changed to AgnocastOnlyCallbackIsolatedExecutor for AGNOCAST_EXECUTOR option.

How was this PR tested?

• Evaluator passed: https://evaluation.tier4.jp/evaluation/reports/3ee70e2f-cf2b-5e96-a27d-ca56d525fecf?project_id=x2_dev
• Verification in Lsim (both ENABLE_AGNOCAST=0 and ENABLE_AGNOCAST=1).

Notes for reviewers

Please review the following aspects:

• Verify that all relevant CMakeLists.txt for shape_estimation node have been updated (no missed files).

  • Our current target is X2 v4.4.0, so please let us know if we have applied CIE to any nodes that do not run with that version.

• 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 rclcpp::executors::SingleThreadedExecutor or rclcpp_components::component_container
  2. The node has multiple callback groups (the default is one)
  3. Shared variables are accessed across callback groups without proper mutex protection

  Note: Nodes already running on MultiThreadedExecutor (or component_container_mt) are not affected, as their callbacks are already executed concurrently.

Interface changes

None.

Effects on system behavior

None.
