Fused group RMS norm + post-norm silu(z) gate: `out = rms_norm(x) · silu(z)`, the norm taken over the trailing `normalized_shape` group extent (`{vd}` for a per-head norm over `[.., HV, vd]`). `weight` is the optional `[group]` gamma applied after the normalization; an absent `eps` takes the runtime's rms-norm default.
