Fix: Resolve generic ReactiveSequence child IDs

[noah-wardlow]

[written by AI]

ReactiveSequence rejected valid generic child tags such as <Action ID="AlwaysSuccess"/> because its immediate-child check searched the node catalog for Action instead of AlwaysSuccess. Resolve ID for Action, Condition, Control, and Decorator children, matching recursive validation. SubTree lookup and the existing multiple-async-child guard remain unchanged.

Related: PickNikRobotics/moveit_pro#22500. This is the dependency fix for the MoveIt Pro v10.1 consumer update; it does not change the library ABI or package version.

Validation: all 216 BehaviorTree.CPP tests passed in Ubuntu 24.04 / ROS Jazzy with Clang 18. The generic-form regressions reproduced failures against the original parser and pass with the fix. Coverage includes generic node forms, native tags, Subtrees, missing/empty/unknown IDs, and multiple-async-child rejection. pre-commit run -a passed.

The consumer package must be published as ros-jazzy-behaviortree-cpp-picknik=4.7.2-3noble before the MoveIt Pro pin update can build.

Packaging: apt_build_farm#66. Consumer: moveit_pro#22504, targeting v10.1.

📝 Summary

Summary by CodeRabbit

• Bug Fixes
  • ReactiveSequence now correctly resolves generic action, condition, control, and decorator nodes using their configured IDs.
  • SubTree nodes continue to be resolved by element name.
  • Invalid, unknown, missing, or empty generic node IDs are rejected with clear runtime errors.
• Tests
  • Added coverage for generic and native child nodes, SubTrees, asynchronous children, controls, decorators, and conditions.

Walkthrough

Changes

ReactiveSequence validation now resolves generic child tags through their ID attributes. Tests cover valid generic and native forms, execution, and registration errors.

ReactiveSequence XML validation

Layer / File(s)	Summary
Generic child ID resolution src/xml_parsing.cpp	Generic Action, Condition, Control, and Decorator tags use their ID values for registered-node lookup. SubTree remains name-based.
ReactiveSequence XML test coverage tests/gtest_reactive.cpp	Parameterized tests cover six valid XML forms and execution. Regression tests cover multiple asynchronous children, unknown IDs, and missing or empty IDs.

Merge Risk: 🟡 Moderate · up to 13c9f

This change broadens ReactiveSequence XML validation for generic child tags; a compatibility mistake could reject valid trees or resolve the wrong registered node, so the public behavior change should be explicitly accepted before merge.
