ObjectBox Java Database Files

• Add ObjectBoxThreadPoolExecutor, a default implementation of a ThreadPoolExecutor that properly cleans up thread-local Box resources.
• Add methods newCachedThreadPoolExecutor() and newFixedThreadPoolExecutor() to BoxStore to help create instances of ObjectBoxThreadPoolExecutor for common uses.
• Add methods newCachedThreadPoolDispatcher() and newFixedThreadPoolDispatcher() to the Kotlin extension functions for BoxStore to help create common coroutine dispatchers backed by an ObjectBoxThreadPoolExecutor.
• BoxStore.runInTx and callInTx close a write cursor even if the runnable or callable throws. This would previously result in cursor not closed warnings when the cursor was closed by the finalizer daemon.
• BoxStore no longer gets stuck while closing when deleting transactions created in other threads with open relation cursors.
• Admin: the Schema view now shows if external name of types and properties if configured.
• Admin: the Schema view now shows the type as text (e.g. "String") instead of the internal type ID.

Sync

• New Sync protocol V8: using new clients also requires a server update
• Remove superfluous sync listener triggers when sync filters "report updates" (SKIP_TX)
• Sync clients compress earlier: reduces disk storage for outgoing data
• Reworked certificates for Apple platforms
• Removed support for older Sync protocol versions before 2024-09; protocol V5+ is now required.
