WIP toward batch-size support. This first commit is behavior-preserving
at the default B=1 (every new multiplication is by max(1, cfg.topo.b) =
1 today) so all existing tests pass. Follow-up commits will:
- scale the remaining stages (S6/S7/S8/S9/S10 + C1/C2/C3 + FFN + FFN AR)
- add a batch selectbox to the sidebar
- forward b through auto_suggest / auto_explore / auto_hardware
Changes so far:
- TopologyConfig: new b: int = 1 field (batch size).
- memory_layout.per_pe_kv_cache_bytes: * B (each concurrent request
keeps its own KV cache slice).
- stage_rmsnorm / stage_wq / stage_wkv / stage_kv_append /
_per_hop_qkT_pv: FLOPs and activation memory scaled by B; weight
bytes stay fixed (weights shared across the batch).
Verified: 24 pytest tests still pass at default B=1.
