message command aliases don't run the message function on commandkit@dev

[FilipoMC]

import { CommandData, CommandMetadata, MessageCommand } from "commandkit";

export const command: CommandData = {
  name: "testing",
};

export const message: MessageCommand = async (ctx) => {
  ctx.message.reply("works");
};

export const metadata: CommandMetadata = {
  aliases: ["t"],
};

Running:

• The full command (!testing) name works as intended
• The alias (!t) doesn't do anything
• Running !aa which isn't a command results in:
  • [ERROR] │ 12:52:01.411 └ Prefix command "aa" was not found.

Thanks for the detailed report! I was able to trace this down.

The alias itself is registered correctly.
metadata.aliases gets merged into the loaded command's metadata during load (AppCommandHandler.ts, processCommandFile).

The issue is in the final command-resolution step in prepareCommandRun:
after the message is parsed, the handler looks up the command with findCommandByRoute(routeKey, usedCommandOverride).

For a normal message (no explicit command-name override), usedCommandOverride is false, and that false is passed straight through as the allowFlatAliasFallback parameter, which disables the alias-matching loop inside findCommandByRoute.
So !t resolves to null silently instead of falling back to the alias.

As soon as i be free I'll work on decoupling allowFlatAliasFallback from usedCommandOverride so aliases resolve correctly in the normal message-command path, and add a regression test as soon as I'm free.
