Remove duplicated inline body from Novel2MoviePipeline.__call__

[fviolette26]

Problem

Novel2MoviePipeline.__call__ re-implements the entire pipeline inline (~510 lines), but the same logic already lives in the plan_text_artifacts and render_video_artifacts methods on the same class. As a result:

• plan_text_artifacts and render_video_artifacts are dead code — defined but never reached.
• The pipeline logic exists in two copies that can silently drift apart.

Fix

Make __call__ delegate to the existing methods:

async def __call__(self, novel_text: str, style: str):
    print("🎬 Novel to Movie Pipeline Started".center(80, "="))
    await self.plan_text_artifacts(novel_text)
    return await self.render_video_artifacts(style=style)

Behavior unchanged

The extracted methods carry the identical logic, including the unbounded-extraction safety caps (_ensure_extraction_cap, MAX_EXTRACTED_EVENTS, MAX_SCENES_PER_EVENT). Net diff: +2 / −512, no behavior change. Full test suite passes (152 passed, 11 subtests).
