Add Feast, Pit modules and Discord webhook

Introduce two new game modules (FeastManager and PitManager) to handle timed endgame events: announcements, world edits, loot generation, teleportation and escape-prevention logic. Add DiscordWebhookManager to send asynchronous webhook messages (embeds/text) and wire it into SpeedHG and GameManager to broadcast game start/end events. Integrate managers into the game loop and reset lifecycle (startGame), add config entries for Discord, and add corresponding language strings. Also include small tweaks (killer XP reward, minor formatting) and updated resource files.
