Detailed Description

Walks an MTC Task and saves all introspection data (stage tree, statistics, every solution and failure, interface states, per-stage failure explanations) to a JSON file on disk.

Intended for offline triage of MTC planning failures, so the customer can ship a single file back to support instead of needing live RViz access at the moment of failure. Plug it in either as a fallback below PlanMTCTask (to capture only failures) or between Plan and Execute (to capture every plan).

The destination directory accepts:

An absolute path (e.g. /var/log/mtc_inspection).
A path relative to the first configured objectives library directory (e.g. mtc_dumps/eternal_tool_change).
A path beginning with ~ or $HOME, expanded against the current user's home directory.

The file name is always generated as <task_id>_<YYYYMMDDHHMMSSmmm>.json from the task's internal id. The trailing 3 digits are milliseconds-within-second so that rapid back-to-back invocations (e.g. retries inside a Fallback) do not overwrite each other. The absolute path of the written file is exposed on the generated_file output port.

Data Port Name	Port Type	Object Type
task	input	std::shared_ptr<moveit_pro::task_constructor::Task>
output_directory	input	std::string
include_trajectories	input	bool
include_scenes	input	bool
generated_file	output	std::string

Warning: Inherits from AsyncBehaviorBase because, with include_scenes=true and a non-trivial planning scene, JSON serialization + disk write can run for hundreds of milliseconds. A synchronous tick would block the BT executor for the duration.
