Mohamed Mastouri 0d2fb6f8a2 feat(st): COLI_MODEL_DIRS - split model shards across N drives, no duplication
Each extra directory holds a DISTINCT subset of the .safetensors shards (search path, dedup by basename; first-listed dir wins). Demand preads hit whichever drive holds the shard, so concurrent expert loads parallelise across drives and combined capacity is used - a 400 GB container fits across two smaller drives that individually cannot hold it, which COLI_MODEL_MIRROR (a full second copy) cannot do. Composable with the mirror: st_mirror_init matches per-shard by basename against the merged index. st_init stays as a back-compat wrapper over st_init_multi. Verified on RTX 5080 / Windows: 72+70 shards across two NVMes, coherent output, [SPLIT] startup log, decode parity with single-drive at full RAM (0.92 vs 0.89-0.90).
