HyperFrames v0.9.47

HyperFrames v0.9.47 fixes a double-audio bug in exports: a clip whose file name has a space or an accent is now mixed in once, not twice.

The release also has a few fixes for Studio and the CLI:

• HEVC phone video with long-term reference pictures keeps its pixel aspect ratio in Studio.
• check, render and downloads work on drives that don't support hard links.
• Studio Server no longer freezes the app when it saves an edit that Windows briefly holds open.
• An unknown CLI flag now lists the command's real flags, and the error leaves out hidden rename shims.
• check no longer reports GPU stalls from its own pixel reads as the film's warnings. It still reports other GL driver notes, and it counts a line held across a split clip as one hold.

On the engine side, a render service can now hold the render page to the same rules as asset download addresses. It's off by default. In Core, a folder with an index.html counts as a project a step can work on, even when it wasn't found through project discovery. The Caption-highlight catalog block now clears a short word's highlight when the word ends.
