Adds tier3TrapCatalog (Antimagic Field, Necrotic Miasma, Symbol of
Death, Planar Rift) per design doc §6 Tier 3-5 table. Tiers 3, 4,
and 5 share this pool — the doc lumps them together. Antimagic
Field uses a new SuppressesMagic flag (no damage, narrative
suppression beat); the other three deliver dice damage and skip
the unmodelled secondary effects (max-HP debuff, drop-to-0,
teleport) for a later phase.

Adds Flame Jet (3d6 fire), Collapsing Ceiling (4d6 bludgeoning), and
Glyph of Warding (5d8 lightning) per design doc §6 Tier 2. Detect DCs
match the table (Perception/Investigation/Arcana 14). Save mechanics
("DEX DC X half") are not modeled — full dice resolve on a failed
detect, matching the Tier 1 convention from D2a.
trapsByTier now dispatches Apprentice → tier2TrapCatalog. Added
deterministic-pick + variety + range tests for the new tier.

Replaces the flat-percent HP nick from D1e with the design doc's three
Tier 1 traps (Pit, Tripwire Alarm, Poison Dart). Each trap defines its
own detect skill + DC and damage dice; selection is deterministic per
(runID, roomIdx).
resolveTrapRoom now picks a trap, rolls Perception/Investigation, and
either narrates a clean spot (zero damage) or rolls the trap's dice and
applies HP loss with the existing KO-protection clamp. Tripwire deals
no damage but raises the alarm narratively.
Higher-tier zones still fall through to resolveTrapRoomLegacy until
D3a/D4a fill in their catalogs.
