feat: unify set-home command naming across platforms

- Updated the command name from `/set-home` to `/sethome` in the GatewayRunner class for consistency.
- Added a new slash command `/sethome` in the Discord adapter to set the home channel.
- Registered the `/sethome` command in the Telegram adapter to align with the updated naming convention.
