fix(engine): strip query strings from video src when resolving on disk

resolveProjectRelativeSrc now strips query parameters (e.g. ?v=4)
before joining with the project directory. Browsers ignore query
strings when loading local files, but the filesystem resolver was
looking for the literal path including the query — causing video
extraction to silently skip the file and render frozen first frames.
