v0.1.23 — glm-5.2 synth: the fused model now beats every member

Changed

• fusion-coder synth: kimi-k2.7-code → glm-5.2 — the first configuration change driven by the project's own fusion-lift benchmark (bench/, analysis in docs/llm-fusion-audit.md). As synth, kimi emitted 17–19k-char draft-style output on factual/reasoning tasks and dragged the always-on fusion composite to 0.71 — below every solo panel member. With glm-5.2 as synth the same pipeline scored 0.99 vs 0.89 for the best solo member (n=14, blind 3-axis scoring by a model outside all conditions; per-answer methodology control kept solo-glm at 0.89). The fused model now exceeds every individual member — the project's core promise, measured. kimi stays on the panel; fusion-agents inherits the change via its fusion-coder reference.
