A bundle's training variant (header-declared `variant`, filename token as
fallback) now selects its sampling preset: distilled -> ltx2_distilled
(8 steps, cfg 1.0, distilled sigmas engage at <=8 steps), sft/base ->
ltx2_base. The bundle table also pins the pipeline class, so
VideoGenerator.from_pretrained(<bundle>) resolves without an override.
Adds basic_ltx2_5{,_distilled}.py examples (--model-path takes the FILE,
--gemma-root declares the paired encoder root), a README section, and CPU
tests for variant/preset resolution, table integrity, and the examples.
