SolitaryThinker bbbb7ab021 [refactor]: migrate examples/scripts to typed VideoGenerator API; rename api/compat.py to api/translation.py
Move all examples/inference and scripts off the legacy
VideoGenerator.from_pretrained(model, **kwargs) +
generate_video(prompt, **kwargs) surface onto the typed
from_config(GeneratorConfig(...)) + generate(GenerationRequest(...))
convention, including the Kandinsky-5 and DreamX-World examples added
on main after the original migration. git-mv api/compat.py to
api/translation.py ('compat' implied a temporary shim; the forward
translation is its honest permanent role) and repoint all importers,
tests, and doc links.

"The robotic arm is in the process of pouring a transparent liquid into the glass. "
"To the left of the pitcher, there is an opened jar with a similar reddish-brown substance visible through its transparent body. "
"In the background, a vase with white flowers and a brown couch are partially visible, adding to the contemporary ambiance. "
"The lighting is bright, casting soft shadows on the table. "
"The robotic arm's movements are smooth and controlled, demonstrating precision in its task. "
"As the video progresses, the robotic arm completes the pour, leaving the glass half-filled with the reddish-brown liquid. "
"The jar remains untouched throughout the sequence, and the spoon inside the glass remains stationary. "
"The other robotic arm on the right side also stays stationary throughout the video. "
"The final frame captures the robotic arm with the pitcher finishing the pour, with the glass now filled to a higher level, while the pitcher is slightly tilted but still held securely by the gripper."
