Screenity 4.6.0

• Capture now happens at 2× the encode size and is downscaled for greater detail.
• MediaRecorder recordings are now MP4/H.264 instead of WebM/VP9 by default.
• Added a warning on sites that block camera/mic through Permissions-Policy (like facebook.com).
• Custom area recording is now disabled up front on sites that block it.
• System audio warning toasts now appear at the bottom, so they aren't hidden behind Chrome's screen-share picker.
• Fixed an issue where region recordings silently fall back to VP8 and lose the first ~3 seconds.
• When the hardware encoder is unavailable or busy, recording now retries using the software encoder instead of failing.
• Recording now recovers faster after the computer wakes from sleep.
• Cropped recordings now retain their original format instead of being converted to WebM and incorrectly labelled.
• Fixed incorrect bitrate reported dimension calculations on ultrawide displays.
