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.

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).
