# Description

Adds a new how-to guide on things to watch out for for better simulation
performance. There have been a few recent threads on hitting performance
issues due to usages of different collision geometries that can be
watched out for and worked around. This new doc page highlights items to
look out for to achieve better simulation performance.

## Comments

I couldn't find any tests for the docker container building, so I'm not
sure where to add some. I'm happy to do so, and can add tests for some
of the other docker building parameters if desired. I have tested
locally for base and ros2 docker profiles with and without the new
suffix parameter. The default setting is an empty string for the suffix,
so it should be a non breaking change and most users will not notice it
being there. I did not touch the cluster docker environment deployment
since I do not have a cluster to test it with, so this new optional
parameter should not be used in the cluster deployment case.

I noticed that there was some redundant docker image building if the
profile is `base`, so I added a check to only build base explicitly if
the docker profile is not base, since the ros2 profile needs base built
in order to build upon it, which is what I assume the explicit base
building is there for.

# Description

This pull request fixes a bug where `_step_reward` could retain stale
values when a reward term's weight was dynamically changed back to zero.
Previously, when a reward term had zero weight, the computation skipped
updating `_step_reward`, assuming that it would stay correct.
However, if the weight was first changed from zero to nonzero and then
back to zero during runtime (e.g., in curriculum settings), stale
nonzero values could persist, causing incorrect reward visualizations or
logging.

This change explicitly sets `reward_manager._step_reward` to zero when a
reward term has zero weight, ensuring correctness regardless of dynamic
weight changes.

Fixes #2391 

No new dependencies are introduced by this change.

In the event manager, class based event terms are not registered
properly due to a missing type() call. On [line 387
](https://github.com/isaac-sim/IsaacLab/blob/7de6d6fef9424c95fc68dc767af67ffbe0da6832/source/isaaclab/isaaclab/managers/event_manager.py#L387)of
event_manager.py, the check should be

            if isinstance(term_cfg.func, type(ManagerTermBase)):
otherwise, isinstance always returns false (since ManagerTermBase is an
abstract base class, the isintance method will check that term_cfg.func
is derived from ABC, and not ManagerTermBase). Adding
type(ManagerTermBase) resolves the issue.

Adds an "idle_action" parameter to the GR1 pick-place env. The
replay_demo script is also updated to check if envs have an idle action
pre-defined in its config and uses it if present. If not present, the
replay script will continue to use a zero tensor for idle actions.

This fixes errors during demo replay if an env doesn't support a zero
action tensor.
