Fix storyboard breaker: full timelines, binding checks, stale scripts

The storyboard breaker produced half-length episodes and unusable
prompts. Root causes and fixes:

- The prompt mapped each shot to 1-2 three-second lines, so a 3-shot
  segment always stopped at 9 s regardless of its duration. The rule
  now requires the timeline to run from 0 s to the segment duration,
  and save_storyboards rejects any batch whose timeline is incomplete
  or discontinuous.
- Total length was only a sentence in the prompt. read_storyboard_context
  now returns target_total_seconds (chars / 500 per minute) and
  save_storyboards reports progress against it so the agent keeps
  splitting to the end of the script.
- Editing the source text after a rewrite/skip left script_content stale
  and storyboards were split from the old version silently. Episodes now
  store script_source_hash; pipeline-status reports "stale" and
  read_storyboard_context refuses with an explanation.
- @Name mentions were never checked against character_ids (e.g. "@Name"
  while the costume variant was bound), so references silently failed.
  Saves now reject unbound mentions; rules clarify that partial on-screen
  appearances are bound and voice-only characters are not.
- No rule kept on-screen text (rules, captions, red text) out of image
  and video prompts; video models render it as garbled glyphs. Added the
  rule plus a save-time check that ignores negated phrasing.

Template version bumped to 5; built-in skills are now re-synced on
upgrade alongside prompts (user-created skills are untouched).

+- 同一人物有多个造型版本（如「张三」与「张三（戏服）」）时，按剧本此刻的造型选对应版本，换装前后不要混用
+- 屏幕文字：剧本里的规则字、系统提示、字幕、红字，以及纸条、黑板、手机屏幕上的可读文字，一律由后期叠加，不写进 video_prompt / image_prompt；对应画面只写人物看到时的反应，并写明「画面中不出现任何文字」

+Character, on-screen text and length rules (hard constraints; save_storyboards checks them mechanically and rejects the whole batch on failure):
+- Bind a character only when visible on screen; a partial appearance (hands, feet, hair, back view) still counts and must be bound. Voice-only characters (off-screen, behind a wall, outside the door, on the phone) are not bound and get no @ — write "Name (off-screen): 'line'". Every @Name in video_prompt must be in character_ids
+- When one person has several look variants (e.g. "Zhang San" and "Zhang San (costume)"), pick the variant matching the script at that moment; never mix them across a costume change
+- On-screen text: rule text, system prompts, subtitles, red text, and readable writing on notes, blackboards or phone screens are all added in post — never put them in video_prompt / image_prompt; describe only the characters' reaction and state "no text appears in the frame"
+- Length: read_storyboard_context returns target_total_seconds; the sum of segment durations should be close to it (±20%); keep going until the last line of the script — save_storyboards tells you how much is left

 video_prompt 规则（硬约束）：
-- 按 3 秒为一段、每段单独一行换行分隔；description 的每个【镜头N】映射为 1-2 个连续 3 秒段（顺序一致、不遗漏、不新增子镜头），切镜点对齐【镜头N】结构
+- 按 3 秒为一段、每段单独一行换行分隔；description 的每个【镜头N】映射为 1 到多个连续时间段（顺序一致、不遗漏、不新增子镜头）；时间轴必须从 0 秒连续写到段落 duration，最后一行的结束时间必须等于 duration（例如 12 秒段落写满 0-3、3-6、6-9、9-12 秒），不许只写到 9 秒把剩下的时间留给模型自由发挥，切镜点对齐【镜头N】结构
 - 每段先写画面（谁+动作+景别/角度），再写该段时间内的台词/旁白——台词从 description 对应【镜头N】内提取，不要创作 description 之外的新台词
 - 提到场景用 @场景名、提到角色用 @角色名，名字必须与 read_storyboard_context 返回的列表完全一致（用于挂接参考素材图片）
 - 氛围、光线描述取自该段 atmosphere
 - 一个段落内允许切镜（换景别/角度/对象），但不跨场景
 - 用户消息中会告知本次视频模型，按该模型的特性与时长限制调整写法；未告知时按通用视频模型写法
 
+角色、屏幕文字与总量规则（硬约束，save_storyboards 会机械检查，不合格整批退回）：
+- 角色绑定：画面里看得见的角色才绑定；只露手、脚、头发、背影等局部也算出镜，必须绑定。只有声音的角色（画外音、隔墙、门外、电话里）不绑定、不写 @，写成「角色名（画外）：「台词」」。video_prompt 里每个 @角色名 都必须在 character_ids 里
+- 同一人物有多个造型版本（如「张三」与「张三（戏服）」）时，按剧本此刻的造型选对应版本，换装前后不要混用
+- 屏幕文字：剧本里的规则字、系统提示、字幕、红字，以及纸条、黑板、手机屏幕上的可读文字，一律由后期叠加，不写进 video_prompt / image_prompt；对应画面只写人物看到时的反应，并写明「画面中不出现任何文字」
+- 总量：read_storyboard_context 返回 target_total_seconds，全部段落时长之和要接近它（±20%）；必须一直拆到剧本最后一句再结束，save_storyboards 的返回会告诉你还差多少
+
 额外要求：
 - 优先复用 read_storyboard_context 返回的 scene_id，不要凭空创造新场景
 - 段落角色绑定必须来自 read_storyboard_context 返回的角色列表；无角色的空镜段落可传空数组
