Pepijn 5de7aa5a4f refactor(envs): move benchmark dispatch into EnvConfig subclasses (#3272)
* docs(benchmarks): add benchmark integration guide and standardize benchmark docs

Add a comprehensive guide for adding new benchmarks to LeRobot, and
refactor the existing LIBERO and Meta-World docs to follow the new
standardized template.

* refactor(envs): move dispatch logic from factory into EnvConfig subclasses

Replace hardcoded if/elif chains in factory.py with create_envs() and
get_env_processors() methods on EnvConfig. New benchmarks now only need
to register a config subclass — no factory.py edits required.

Net -23 lines: factory.py shrinks from ~200 to ~70 lines of logic.

* docs(benchmarks): clean up adding-benchmarks guide for clarity

Rewrite for simpler language, better structure, and easier navigation.
Move quick-reference table to the top, fold eval explanation into
architecture section, condense the doc template to a bulleted outline.

* fix link

* fix task count

* fix(tests): fix 3 failing dispatch tests

- test_registry_all_types: skip non-EnvConfig stubs (e.g. TestPluginConfig)
- test_processors_delegation: use None instead of abstract PreTrainedConfig
- test_custom_get_env_processors_override: use DataProcessorPipeline for isinstance check (PolicyProcessorPipeline is a subscripted generic)

* fix: enable SmolVLA eval on LIBERO with custom camera mappings

- Thread camera_name_mapping from LiberoEnv config through to gym envs
- Sync features_map with camera_name_mapping in LiberoEnv.__post_init__
- Fix render() to use first available camera instead of hardcoded "image"
- Handle non-dict final_info in rollout by falling back to info["is_success"]
- Add use_peft legacy field to SmolVLAConfig for checkpoint compat
- Add defaults to GR00TN15Config init=False fields for transformers 5.3

Made-with: Cursor

* fix: use direct AutoresetMode import for gymnasium compat

Made-with: Cursor

* fix: handle gymnasium < 1.0 without AutoresetMode

* refactor: revert policy changes, keep env-only camera mapping fixes

- Revert GR00T N1.5 default_factory/default changes (transformers compat)
- Revert SmolVLA use_peft legacy field
- Apply ruff formatting fixes
- camera_name_mapping stays entirely in env/eval layer (no policy changes)
