* feat(studio-server): accept a crf override on the render route The Studio render route only forwarded draft/standard/high, so a Studio or desktop export could not ask for a specific CRF the way `hyperframes render --crf` can. Film-grain finishing passes need CRF 12 to keep the grain. The route now takes an optional integer `crf` (0-51 for mp4, 0-63 for webm), rejects an out-of-range value with 400 instead of dropping it, ignores it for mov, and both Studio adapters pass it to the render job.

Parsing moves to helpers/encoderOptions.ts. Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com> --------- Co-authored-by: Claude Opus 5.5 (1M context) <noreply@anthropic.com>
