single-instance v2.3.1

[2.3.1]

• 6f345870 (#2860 by @MorpheusXAUT) Fix D-Bus name replacement logic on Linux to prevent multiple instances from acquiring the same well-known name.
  This patch updates the zbus dependency to the latest compatible version (^5.9) and explicitly sets RequestNameFlags to ensure a second instance fails to acquire the D-Bus name when another one is already running.
