Release v3.2.2

• Redesign /config: the ten separate /config set-* subcommands are replaced by a single /config set <key> <value>, and /config get <key> now shows one setting's current value, accepted input, and how to change it (omit the key to list everything). Settings are picked from a dropdown of keys, and set accepts friendly values such as true/false/yes/no for toggles with clear validation errors. All /config replies are now private (ephemeral), so viewing or changing settings no longer posts to the channel.
• Remove the /autoplay command in favor of /config set autoplay true|false, so every per-server setting is managed through /config. Autoplay behavior is unchanged and remains on by default.
• Add a /help command that lists every available command and its description in a private (ephemeral) reply. The list is generated from the live command registry, so it always reflects the commands that are actually installed.
• Align the bot's persona and branding with Mochi's East-Asian theme: reword user-facing replies (the error prefix ope becomes aiya, the u betcha confirmations become hai, and the /clear, /pause, and /resume flavor text is rethemed), rename the Compose data directory from muse/ to mochi/, and replace the logo with a new mochi logo.svg.
