Migrate client tick subscribers

@@ -24,6 +24,7 @@ The Gitea runner has been used for:
   - `BlockIndexManager`
 - Updated the `ExplosionMixin` complex constructor injection descriptor for Minecraft `1.21.1` after a client bootstrap crash showed the old Forge `1.20.1` constructor target no longer exists.
 - Updated `GameRendererBlurMixin` render callback and invoke descriptors for Minecraft `1.21.1` after the next client crash showed `GameRenderer#render` now receives `DeltaTracker, boolean`.
+- Replaced client tick subscriber parameters that used the temporary `compat.TickEvent.ClientTickEvent` placeholder with NeoForge `ClientTickEvent.Post` after mod loading rejected non-Event subscriber parameters.
 - Fixed runner setup issues:
   - executable `gradlew`
   - tracked `gradle-wrapper.jar`
