v0.55.0

Changes since v0.54.0:

Performance

• real-text H100 board — e2e 4/6 wins, decode 5/6, q35 decode flipped; q9 f16 mirrors per-model gated
• q35 shexp fused sigmoid-dot (+13.7% H100 decode), E4B head-last prime (111x prefill), matmul_pre empty-fallback guard
• g26 expert-down through the int8-MMA expert GEMM — H100 prefill 2901 -> 5042 tok/s (1.74x)

Fixes

• board prompt fox-repeat -> real text; recover uncommitted board evidence
• segment exec-update captures at kernel-class boundaries — q35 graph gate green
• route gemma4 through its dc/graph twins on the device-counter entry points
• decode-batch gate1 multi-seed recalibration; round 45 ledger

Documentation

• H100 board shows e2e tok/s per model — one number per arm, no pp/decode split
