refactor: flatten monorepo to single web package (#12)

Flatten the pnpm monorepo (apps/web + packages/*) into a single web package at the repo root.

- Move app/lib/components/scripts/public to root; drop apps/web and packages/* wrappers
- Rewrite tsconfig paths (@infiplot/*) to ./lib/*; turbopack.root = __dirname
- Update Vercel (no root-directory) and Cloudflare (pnpm build:cf at root) deploy paths
- Regenerate pnpm-lock.yaml to drop stale workspace importers
- Bump engines.node to >=22 to match wrangler

The atmosphere is tense and apocalyptic, rendered in a retro 16-bit pixel art style with a limited color palette. Vibrant cyan grid lines contrast against the stark white of the falling eraser. High-contrast lighting, dramatic shadows, geometric destruction, 16-bit aesthetic, vintage game graphics, no characters present.","beats":[{"id":"b1","narration":"耳边传来震耳欲聋的摩擦声，整片白色大地在剧烈颤抖。你抬头望去，一块遮天蔽日的白色矩形——橡皮擦，正带着毁灭的气息碾压而来。","next":{"type":"continue","nextBeatId":"b2"}},{"id":"b2","narration":"你身边的‘E=mc²’像素块瞬间粉碎成渣，逻辑正在被物理抹除。再慢一秒，你就会变成一堆毫无意义的石墨粉末。","speaker":"你","line":"开什么玩笑……我可是顶级黑客，怎么能死在这这种鬼地方！","next":{"type":"continue","nextBeatId":"b3"}},{"id":"b3","narration":"生死关头，你注意到左前方有一滩尚未干透的蓝黑色墨水渍，那里是规则混乱的盲区；而正上方，那双名为‘造物主’的巨大眼睛正透过镜片冷漠地注视着纸面。","speaker":"你","line":"拼了！到底是躲进阴影，还是赌她会停手？","next":{"type":"choice","choices":[{"id":"c1","label":"跳入深色墨水渍","effect":{"kind":"change-scene","nextSceneSeed":"墨水渍内部是混乱的16-bit废墟，你在这里遇到了那个自称‘黑影’的家伙"}},{"id":"c2","label":"拼成SOS求救","effect":{"kind":"change-scene","nextSceneSeed":"巨大的笔尖停在你面前，苏清月疑惑地靠近纸面，你第一次近距离看清这位造物主的脸"}}]}}],"entryBeatId":"b1","sceneKey":"draft-paper-grid-white","imageUuid":"95a0f0bb-961b-4e0c-9728-68f809c68619","imageUrl":"https://im.runware.ai/image/os/a05d22/ws/3/ii/95a0f0bb-961b-4e0c-9728-68f809c68619.png"},"imageUrl":"/home/firstscene/m27.webp","characters":[],"storyState":{"logline":"命悬一线的草稿纸火柴人，如何操纵现实世界的“造物主”，在被彻底抹除前逆天改命？","genreTags":"脑洞快穿 / 爽剧 / 元叙事 / 像素风生存","protagonist":"你曾是现实中被陷害的顶级黑客，意识意外坠入死对头女儿的草稿纸上。此刻你不仅失去了实体，还面临物理意义上的“抹除”。你必须利用16-bit世界的底层逻辑生存下去，并试图向纸外的现实世界复仇，你的软肋是只要纸张湿透，你的记忆就会永久溶解。","castNotes":"苏清月：手持画笔的“造物主”，看似清纯内向的艺术生，实则在草稿纸上发泄着极其阴暗的杀戮欲望；她是唯一能改写你命运的人。\n黑影：纸张折痕处生存的“涂鸦前辈”，性格乖张狡诈，曾多次从橡皮擦下逃生，他知道跳出这张纸的方法，但需要拿你的意识做交易。","synopsis":"你在死对头女儿的草稿纸上以火柴人身份苏醒，在橡皮擦的灭顶之灾中极限逃生。你意识到自己必须在被彻底抹除前，利用纸上的规则向外界传递信号。","openThreads":["导致你意识坠入草稿纸的幕后黑手身份","苏清月在草稿纸边缘画下的那些诡异血腥图案的含义"],"relationships":["苏清月：视你为随手涂鸦的造物主，目前尚未意识到你的自我意识"],"nextHook":"无论你选择躲藏还是求救，你都即将接触到这个纸面世界背后的第一个禁忌——苏清月的阴暗面。"},"cardName":"m27","cardTitle":"草稿纸里的我","cardGender":"男性向","worldSetting":"这是一款面向【男性向】观众的 AI 交互剧情游戏，整体走红果短视频式的强戏剧冲突与快速反转。\n剧情风格：多线转折。内容节奏：紧凑爽快。\n精选剧情《草稿纸里的我》的开场设定：睁眼发现自己是一张草稿纸上的火柴小人，住在 16-bit 的网格世界里。橡皮擦从天而降，正在抹掉这一行字——也包括我。\n请直接以此开场切入，给玩家强烈的代入感与爽点；后续分支保持短剧式的反转密度，让玩家每一次选择都能立刻看到回响。","styleGuide":"像素风格，复古游戏 16-bit 调色，方块化几何造型。","imageUrlRemote":"https://im.runware.ai/image/os/a05d22/ws/3/ii/95a0f0bb-961b-4e0c-9728-68f809c68619.png"}
