v2.4.6 - Launch and split mirroring stability improvements

What's new

This release focuses on mirroring startup stability, split layout transitions, and secure relay recovery.

Improved launch and stream recovery

• Improved startup reliability when the first frame is delayed or missing
• Reduced false ready/reuse decisions caused by stale stream metadata
• Improved automatic recovery flow when a stream does not recommit correctly
• Added deeper diagnostics for launch, barrier, stream bootstrap, and first-frame timing

Better split and layout transition behavior

• Fixed cases where split mode could briefly show an incorrect temporary layout before settling
• Improved split target handling so the correct pane sizes are applied from the beginning of launch
• Improved relaunch behavior across single, split, and popup transitions
• Refined same-target no-op logic so relaunch is skipped only when the current state is truly reusable

Certificate and relay reliability

• Added automatic recovery for corrupted dynamic PKCS12 certificates
• Improved HTTPS relay startup reliability when local certificate state is invalid

Notes

• This update mainly targets stability, recovery behavior, and internal diagnostics
• No major user-facing workflow changes were introduced, but mirroring startup and recovery should feel more reliable
