Adds example documentation for a new model or environment in RLinf (RST pages in the docs gallery for both English and Chinese). Use when adding a new embodied or reasoning example, or new benchmark (e.g. LIBERO, ManiSkill).

Adds install command in install script, Docker build stage in Dockerfile, and CI jobs for docker build, install script, and embodied e2e test when introducing a new model or environment in RLinf. Use when adding a new embodied model (e.g. dexbotic), new env (e.g. maniskill_libero), or new model+env combination that should be installable, dockerized, and tested in CI.

Cross-checks RLinf documentation against code and other docs, including English-Chinese parity checks. Use when adding or editing docs, reviewing doc PRs, validating commands/config keys/model-env names, or ensuring EN and ZH docs stay consistent.
