CI Bot	492ae582e8	feat: 绿幕抠像 + 音频降噪引擎新增两个渲染能力：【绿幕抠像 ChromaKeyEngine】 - 基于 FFmpeg colorkey 滤镜，支持绿幕/蓝幕/红幕 - 可配置：抠除颜色、相似度、边缘平滑、溢色抑制 - 5种预设：green_screen/blue_screen/red_screen/precise_green/soft_green - 从 clip.config.chroma_key 读取配置，零侵入数据模型 - 降级策略：参数越界自动钳制，解析失败不阻断渲染【音频降噪 NoiseReductionEngine】 - 基于 FFmpeg afftdn 滤镜（短时傅里叶变换降噪） - 3档预设：低/中/高 + 自定义阈值（-60~-5 dB） - 人声增强模式：highpass + compressor + loudnorm - 从 plan.config.audio_noise_reduction 读取配置 - 降级策略：参数越界自动钳制，降噪失败用原始音频【系统集成】 - 绿幕抠像：UnifiedRenderService Step 1 接入（scale之后，fps之前） - 支持 filter_complex 路径 + 直通模式双路径 - 音频降噪：后处理模式，在 mix_audio 最终输出前应用 - filter_complex 路径通过 RenderContext 传递配置 - 直通模式通过 -af 参数应用 69个新增单测 + 1435个现有测试 = 1504个全绿，零回归	2026-07-14 10:41:58 +08:00
