New functionality with event schedule

1. It is necessary to find the most detailed schedule of events (like here [LINK](https://tl.plaync.com/en-sg/schedule/index))
2. Process it properly to extract the necessary data
3. Transfer this data to the AI ​​assistant and add a new listener for the discord bot

No files, tests, or entry points are named. Start by inspecting the bot's existing event-listener integration and the linked Throne and Liberty schedule source, then determine how schedule data reaches the AI assistant. Done means the schedule is extracted reliably and a Discord listener exposes the resulting event information.
