The i2v detector matched any path containing 'i2v' without excluding 't2v',
misrouting T2V checkpoints stored under i2v-containing directories. The
variant detectors all require lite/pro tokens, so the model_index _class_name
fallback ('kandinsky5t2vpipeline') could never match and I2V-Lite-distilled
checkpoints had no detector at all; add base T2V/I2V fallback registrations
after the variants. Also fix the registered Lite distilled repo to the real
kandinskylab/Kandinsky-5.0-T2V-Lite-distilled16steps-5s-Diffusers (the old
name 404s) and correct the example comments.

text_encoder_cpu_offload=True makes the Qwen encoder compute on CPU, where
flash-attn has no kernels; with flash_attn installed both examples crash in
the first text-encoding forward. The offloaded path only worked in envs
without flash_attn via the silent SDPA fallback.
