Screenity 4.5.3

• Fixed "can't load your recording" errors on big files that timed out while loading.
• You can now cancel a download that's taking too long, like a slow WebM conversion, instead of being stuck waiting.
• Saving as WebM now handles large recordings without running out of memory
• More reliable recording starts, especially when Chrome restarts the extension in the background, with automatic retries on transient failures.
• Recordings that captured content but got interrupted while stopping are now recovered and saved instead of discarded.
• Fewer false recording failures on backgrounded or static screens.
