Subject: [PATCH] fix(run-swift15-bf16): per-mode engine pins + explicit KV
 pools

kld stays on 1.0.13 (record on the scoring engine) with --vram-kv-mib
4608 + 16 slots: the ratio-derived pool came up SHORT by 217 MiB at
32x16k. calib moves to 1.2.0: the RADIANCE_CALIB_TOKENS tap is a 1.2.0
qwen4exp plugin feature (1.0.13 plugin has the DIR half only), and
Grams are bf16 activations - engine-invariant. --vram-kv-mib 9984
covers 64x16k fp8 slots.
