Directory rename (git mv, history preserved) plus rewrite of all references: absolute imports in tests, the zero-dep runner, docstrings, comments, and the README. No behavior change. Run: python3 -m pytest v2/tests/ -q ; python3 v2/run_tests.py ; python3 -m v2.examples

"""Wan2.1 T2V program (design_v3 §13, §15a): text_encode → diffusion_denoise → vae_decode.

The text-encode node demonstrates the content-hash feature cache (design_v3 §7.2, §10): the
|
||
same prompt across requests (e.g. a K=24 RL group) encodes once and reuses — the 24× text-encode
|

reduction the vendored RL sampler cannot express.
