1.18.4-beta.1

Notice: Vibeshine may trigger false-positive antivirus alerts. Details and workarounds are documented here: #59

Updated libvirtualdisplay to v1.6.3 so a failed virtual-display teardown no longer blocks later virtual-display creation.
Prevented completed sessions from reviving stale virtual-display recovery while the physical desktop is being restored.
Ensured virtual-display DPI changes target only verified virtual monitors, never the Windows primary physical display.
Deferred idle display probing and topology readiness checks until the interactive desktop or requested topology is actually ready, avoiding stuck temporary displays at startup.
Preserved automatic and fractional display refresh-rate policies, including across delayed virtual-display activation.
Kept encoder-probe ownership tied to the captured GPU and restored display topology before releasing retained virtual targets.
Normalized Playnite autosync identifiers so existing entries are not missed or purged because of letter-case differences.
