LTXCaps gains a `variant` field ('0.9', '2.0', '2.3') replacing
`is_ltx_2_3`; variant-specific branches check `caps.variant == '2.3'`
instead of grepping the model name.
ltx_util.load_upsample_2x mirrors load_upsample's contract so the 2.x
path owns a module-level cache and stops reloading ~2.3 GB every run.
The cached pipe is stamped with a synthetic
`CheckpointInfo('ltx-upsampler-2.x')` so it gets its own OffloadHook
slot and can go through apply_balanced_offload without invalidating
the main pipe's module map. The hardcoded `.to('cpu')` and post-pass
torch_gc are gone; the second apply_balanced_offload handles spill.
video_overrides comment on OzzyGT LTX-2.3 connectors states plainly
that mirrors pack weights twice by design; ignore_patterns is the
surgical workaround, not an hf_hub bug.
Drive-by: load_upsample log line used `__class__.__name__` (always
'type'); switched to `__name__`.
