Pull request overview

This PR contains multiple experimental changes primarily focused on robotic manipulation tasks, including adjustments to task configurations, termination conditions, backup controller implementations, and dependency updates. The changes appear to be exploratory and developmental in nature, involving modifications to vial insertion tasks, object stacking logic, and ensemble-based policy execution.

Changes:

• Updated termination logic for object insertion and stacking tasks with modified thresholds
• Added new backup controller implementations for different task types (place, insert)
• Modified ensemble evaluation parameters and switching logic
• Updated dependency versions and Docker configuration settings

• The function object_inserted_upright is returning stacked instead of the locally-defined inserted variable (which was the original return value on line 214). This changes the function's behavior from checking if an object is properly inserted upright to only checking if it's stacked, ignoring the upright validation. This appears to be an unintended logic change that could break insertion task validation.

• Uncommented debug print statement should be removed or replaced with proper logging. Debug print statements left in production code can clutter output and impact performance.
  source/isaaclab_tasks/isaaclab_tasks/manager_based/manipulation/cube_lift/lift_env_cfg.py:1
• Episode length changed from 500 to 5000 seconds. This appears to be a 10x increase that likely represents 5000 timesteps rather than 5000 seconds. The variable name episode_length_s suggests seconds, which would make this an unrealistically long episode (over 83 minutes). Either the value is incorrect or the variable is misnamed.
  source/isaaclab/setup.py:1
• The version 'flatdict==4.0.0' does not exist. The latest available version of flatdict is 4.0.1. This will cause installation failures.

Corrected spelling of 'Uncertaity' to 'Uncertainty'.

Suggested change

	print(f"Uncertaity in joint {joint_num} triggered")
	print(f"Uncertainty in joint {joint_num} triggered")

Isaac Sim version downgraded from 5.1.0 to 5.0.0. While setup.py was updated to support Isaac Sim 5.1.0 (line 84), the Docker configuration uses an older version. This version mismatch could lead to compatibility issues.

The variable 'diff' is hardcoded to 0 and never calculated, yet it's returned in the metrics dictionary. Either implement the intended calculation or remove this unused metric.
