Add RoomSecret (5% chance) and RoomMiniBoss room types. Add 4 mini-boss
monsters at 60% of boss stats (Guardian's Herald, Warden's Shadow,
Overlord's Lieutenant, Archlich's Harbinger) with IsMiniBoss flag and
boss pattern logic. Secret rooms grant double treasure. Mini-boss rooms
are placed on floors 4/9/14/19 at room index 1.

Implement RandomEvent system with 8 events (altar, fountain, merchant,
trap_room, shrine, chest, ghost, mushroom), each with 2-3 choices that
resolve based on floor number. Update triggerEvent() to use the new
system, auto-resolving a random choice on a random alive player.

effect damage on matching floors. Realign boss patterns to match themes
and add PatternFreeze for the Glacier boss.

Elite monsters have ~20% spawn chance with Venomous, Burning, Freezing,
Bleeding, or Vampiric prefixes. Each prefix scales HP/ATK and applies
on-hit status effects (or life drain for Vampiric).
