fix(video-pipeline): 修正清单字段存在性校验逻辑

将 `cmd-init.js` 和 `cmd-validate.js` 中的虚值校验（`!item[f]`、`!item.script && !item.text`）改为更精确的字段存在性校验（`!(f in item) || item[f] == null`、`!('script' in item || 'text' in item)`），避免因空字符串或零值等合法空输入导致误报错误。

 - **色彩体系：** **褪色中的暖金**——暖金色时段光线主导画面中心（梦核），朝画面边缘逐渐冷却为冷蓝灰与暗紫调（不安氛围）。整体中低饱和度，暖色主导、冷色从边缘渗入。核心原则：光在画面中发生了微妙但无法忽略的变化

-Ultra-realistic cinematic photograph in the style of dreamcore liminal space with an undertone of quiet unease. A familiar childhood space — a hallway, a classroom, a swimming pool, a playground — extends into dimensions that feel subtly off. The space is clean and still, almost too still — the unease comes from the subtle wrongness in the proportions, not from anything in the dark. Warm golden hour light fills the center of the frame but gradually cools into muted blue-grey and dusky purple toward the edges, as if the light itself is slowly shifting. A single warm practical light source (incandescent bulb, window) has a color temperature that changes along the length of the space — same type of fixture, different color of light at the far end. Thin atmospheric haze fills a space where mist should not exist — a school corridor, an indoor pool hall, a bedroom — softening the edges of familiar objects. Dramatic Tyndall effect volumetric light beams pierce through the still air, revealing suspended particles frozen mid-float. The walls and surfaces are clean but the proportions feel subtly wrong — doorframes slightly too tall, ceilings a bit too high, the corridor just a little too long for the building it appears to be. A mirror reflection where the reflected window is positioned slightly differently than the actual window in the room — you notice it but cannot quite confirm it. A shadow among several from the same light source that stretches noticeably longer than the others. Mist with uneven density — one patch thicker and catching light differently than the surrounding haze. The air itself has a subtle weight in certain corners — a density that does not match the rest of the room. An unseen presence suggested only through spatial wrongness — the architecture feels larger than it should be, the empty doorframe leads to a corridor whose vanishing point is slightly too luminous and the wrong color. Color grade: fading warm golden light in the center, desaturated blue-grey undertones bleeding in from the edges. Nostalgic but quietly unsettling — a half-remembered dream that you now realize might not be yours. The unease is not in what you see — it is in what you cannot quite confirm, the proportion that shifts in your peripheral vision, the reflection that may not match. No creature, no monster, no gore, no body horror, no organic growth, no jump scare framing. High sharpness on the focal subject with natural cinematic depth of field falloff. Cinematic film grain texture. Full bleed, edge-to-edge composition, no border, no frame. No text, no watermark, no logo. Horizontal format, aspect ratio 16:9.
