- Adjusted condition to prevent unnecessary "one guildstone per house" restriction when moving the guildstone inside the same house since the guildstone does not disappear after teleporter generation.
Refactors the teleportation logic for improved user experience.
### Summary
* Bumps to .NET 9 with updated dependencies
* Comparing a value type against null is no longer allowed
* CI/CD now uses the version specified in global.json
* Serialization generator updated to .NET 9 with bug fixes, fixes to turkish language, and parallelization
### Summary
Fixes a few minor issues with timers:
- Timer.Delay and Timer.Interval was not reflecting the actual tick time (aligned to the next 8ms)
- Negative delay values were causing a crash when DateTime.Now - delay was below DateTime.MinValue
- Timer.Next now reflects the correct wall clock tick time based on the adjusted Delay.
- Timer.Next is not assigned when the timer is started. This was important for timers that were created, but started later.
- Fixes double return issue with object property list that is causing corruption.
- Adds DEBUG_ARRAYPOOL define constant which will crash on double return or invalid return scenarios.
> [!IMPORTANT]
> **Developer Notes**
> STArrayPool rented arrays **MUST NOT** be returned **ONLY ONCE** otherwise there will be corruption from double-use.
> Use `DEBUG_ARRAYPOOL` to test potential broken STArrayPool use cases.
> [!NOTE]
> **Why can't I enable the debug all the time?**
> Other than the fact that it will crash due to bad code, the actual tracking system is highly detrimental/problematic for performance and memory consumption by creating objects that have a stack trace.
### Summary
- Puts back `EventSink.SocketConnect`.
- Reverts networking change to push the networking to a separate thread.
- Reverts changes to the firewall by removing the firewall queue.
- Fixes listeners not shutting down with the server.
- Fixes race condition causing connections to get stuck even after they are disposed.
> [!NOTE]
> **Developer Note**
> Networking has been reverted back to using the main thread instead of a background thread. This alleviated complexity and the requirement for concurrent queues all over the place.
