An Android 160.7 crash report points to MessageQueue sending an oversized command. If the timer runs after disconnect, Call.sendChatMessage routes it to the local handler, which throws ValidateException and closes the game. This can disrupt joining or reconnecting to servers.

Validate the text limit before queuing and sending, discard commands when their connection or world changes, and contain validation failures. Commands are never truncated or split; local/host delivery and the existing rate limit are preserved.

Verified:

• Reproduced the original timer crash with official Mindustry 160.7 classes; the patched callback clears the stale queue without throwing.
• Nine regression tests pass against 159.7 and 160.7, including native local/host command delivery.
• Android/desktop JAR builds successfully.
