ZE FusionBot v8.0.1

[Secludedly]

Fixed More Memory Leaks I Missed in Previous Commit
Thanks to @link2026 & @NexusRisen
v8.0.1

BotSource.cs

• Class now implements IDisposable.
• Stop() captures the current CancellationTokenSource in a local, swaps in the new one, then disposes the old one in
  the HardStop continuation. No more leak on stop/start cycle.
• Dispose(bool disposing) is protected virtual so RecoverableBotSource can chain to it.

---

RecoverableBotSource.cs

• No longer redundantly declares IDisposable (inherits it now).
• Dispose(bool) is protected override and calls base.Dispose(disposing) so the base CTS gets cleaned up.

---

BotRunner.cs

• Remove(...) now disposes the BotSource after removing it from the list.

---

SysCord.cs

• Class implements IDisposable.
• _services re-typed from IServiceProvider → ServiceProvider and disposed.
• DM relay now stored in _dmRelayService field instead of _ = new DMRelayService(...), and disposed.
• The previously-anonymous Disconnected lambda is now a Client_Disconnected method so it can be -='d.
• Per-bot ConnectionSuccess / ConnectionError lambdas are captured into a _tradeBotUnsubscribers list and unsubscribed
  on dispose.
• Dispose() unsubscribes every Discord/Commands/Interactions handler (Log, PresenceUpdated, Disconnected, both Ready
  handlers, MessageReceived, InteractionCreated) and disposes _dmRelayService, _services, _reconnectCts,
  _reconnectSemaphore, and _client.
• MainAsync's finally now delegates cleanup to Dispose() rather than disposing things piecemeal.
