Welcome and goodbye messages now use a more detailed LayoutView with sections for member info, server statistics, and dynamic styling.
- Welcome messages display total server members and the new member's account age.
- Goodbye messages show current member count, the leaving member's join date and time in server, with dynamic colors and titles for leave, kick, and ban events.
- All command feedback for welcome/goodbye configuration, testing, and error handling has been updated to use rich Discord Embeds for improved user experience.
Removes the dedicated error handler for the `disable_goodbye` command.
This allows for more centralized or general error handling to take over.
Adds a log message when the WelcomeCog is successfully loaded.
Migrates individual command error handlers to the cog-wide `cog_command_error` method. This simplifies error handling by automatically catching errors from all commands within the cog.
Adds `ephemeral=True` to error messages sent to the user and logs the `original_error` for better debugging.
Integrate `discord.ui.LayoutView` to provide richer, more structured welcome and goodbye messages with user avatars and accent colors.
The `on_member_remove` event now utilizes audit logs to determine if a member was kicked or banned, providing more context in goodbye messages.
Add `testmessage` command group with `welcome` and `goodbye` subcommands to allow administrators to easily test message configurations.
Replace development-time `print` statements with standard `logging` for cleaner output and better debugging.
