Package-level declarations

Intercepts every incoming chat message at the lowest level (the private addMessage that all of addClientSystemMessage / addServerSystemMessage / addPlayerMessage funnel into) so JIM's `chat` trigger can read and optionally cancel it.

Feeds the spawnParticle trigger from the client level.

Feeds the messageSent trigger; cancelling blocks the outgoing chat message.

Feeds JIM's packetReceived / packetSent triggers.

Drives the renderEntity / postRenderEntity triggers and JIM's Tessellator matrix API.

Adds a transient back-reference to the source entity on every entity render state.

Feeds the actionBar trigger; cancelling hides the overlay (action-bar) message.

Feeds the entityDeath trigger.

Feeds the soundPlay trigger — every sound that reaches the engine.
