合并 master 的付费生成预检与调试输出脱敏

合入 master 的编辑器付费生成目标预检与应用状态调试输出密钥泄漏两项修复。 SFX 直连与入队沿用 master 预检，源码顺序回归改为锁定本分支的 ElevenLabs worker 编排入口。画布 Agent 音效参数恢复通用 null 缺省兼容，但保留 duration null 表示自动时长的 SFX V2 语义。音效时长越界断言按 SFX V2 的 0.5-30 秒边界上移，重算契约测试期望。哨兵测试补入 ElevenLabs base URL 与 API key，锁定其默认缺席于 AppConfig 调试输出。

				game-chat 的 code-director 是程序侧资产审计节点。第一步必须调用 `asset.list` 核对当前正式资产、Canvas 登记和可复用状态；不得生成图片、修改游戏或只凭用户措辞猜测缺口。取得 asset.list observation 后，本轮必须调用 `agent.route_manifest` 提交结构化结果：Supervisor 选择 audit-existing-first 且没有缺口时使用 `strategy=use-existing-art, missingAssetSlots=[]`；存在缺口时使用 `strategy=generate-missing-art`，missingAssetSlots 只能精确列出 `art-spec`、`core-spritesheet` 中实际缺失项；Supervisor 选择 regenerate-art 时使用 `strategy=regenerate-art, missingAssetSlots=["art-spec","core-spritesheet"]`。Runtime 会复核权威资产状态，拒绝遗漏、虚构、过期或重复缺口。路由成功后再交付只读审计结论；美术补齐后由同一根 Run 恢复 code-prototype。
