Adv 2.0 D&D Phase 11 D3c: Tier 2 zone flavor files

New additive flavor files (zone_forest_shadows_flavor.go,
zone_sunken_temple_flavor.go) with elite-room intros, boss ability
callouts, and zone lore. Reuses existing RoomEntryForestShadows and
BossEntryHollowKing from twinbee_gm_flavor.go. The Sunken Temple had
no canonical RoomEntry/BossEntry pools yet, so both are defined in the
new zone file.

  Hollow King: Corrupting Aura / Root Surge / Devour Light / Phase Two
  Dreaming Aboleth: Tentacle Multiattack / Enslave / Mucus Cloud /
    Legendary Actions

Wires zoneRoomEntryPool, bossEntryPool, zoneLorePool,
bossSignaturePool, and eliteRoomEntryPool to the new tier-2 pools.
Updates the D2b "no callout pool" test to use Dragon's Lair (still
unflavored) and adds Tier 2 routing tests for boss-entry, elite line,
lore, and room-entry overlays.

+// Tier 2 zone flavor — Forest of Shadows. Additive only. Pools sampled by
+// internal/plugin via deterministic per-run, per-room hashing.
+//
+// Voice rules (from gogobee_dungeon_zones.md §3.3):
+//   • Third person for description; second person for outcomes.
+//   • Boss callouts get a beat of cinema. Don't overrun.
+//   • TwinBee references the right era — NES, SNES, arcade. Not modern.
+//
+// Room-entry and boss-entry pools for this zone live in the canonical
+// twinbee_gm_flavor.go (RoomEntryForestShadows, BossEntryHollowKing) and
+// are not duplicated here. This file adds elite-room intros, boss
+// ability callouts, and zone-specific lore.

+	"The path ends at a pond that shouldn't be a pond — too still, too dark, the wrong kind of reflective. A figure is wading at the far edge, washing something that probably wasn't laundry. She turns. She smiles. TwinBee says, very quietly, 'green hag,' and stops there.",
+	"You smell the cooking before you see the cook. Sweet, herbal, faintly wrong. The clearing ahead has a fire, a pot, and a woman who is too tall and too thin and whose teeth are arranged with a creativity that a normal mouth could not justify. TwinBee suggests not eating anything she offers.",
+	"A circle of toadstools, perfectly spaced. In the center, a stump with a teacup on it. Steam still rising. TwinBee identifies the trap structure on instinct — fey hospitality, hag rules, a rite that asks one question and punishes wrong answers permanently.",
+	"The forest gets quieter the way a room gets quieter when the host walks in. She's already in the clearing when you arrive — bone necklace, briar crown, eyes the color of pond-bottom. 'Travelers,' she says, the way someone says 'lunch.' TwinBee straightens up.",
+	"The trees here are leaning in, not away. That's the tell. TwinBee notes the change in posture and looks for the center the trees are listening to. The center is the hag. The hag has been listening back.",

+	"The air around the Hollow King isn't air. It's the absence of something — focus, intent, the part of you that decides the second small action of a turn. TwinBee notes the WIS DC 14 and recommends ranged.",
+	"His aura presses on you the way a closed room presses on a held breath. Bonus actions become a gamble. TwinBee files this under 'positional' and recommends accordingly.",

+	"The ground splits. The roots come up coordinated, like fingers — TwinBee uses the word 'fingers' deliberately and dislikes itself for the accuracy. Restrained on a fail. TwinBee suggests breaking free as a priority.",
+	"Like the vine traps in Castlevania III's stage 5 — except the vine is also a damage source and also a lock on your action economy. TwinBee respects the multitasking and resents the design.",

+	"Every magical light in the room dims to nothing. The natural torchlight remains, dimmer than it was. TwinBee says: 'AC penalty for two rounds. Fight smarter or fight harder. Both works.'",
+	"The forest gets darker in a way that wasn't there a moment ago. TwinBee can still see — TwinBee always can — but the AC -2 is real and the next round of attacks will feel it.",

+	"The antlers bend back, the eyes lose what was left of their mercy, and somewhere in the forest something with paws starts running toward you. Two dire wolves, incoming. Reckless Attack on the boss — advantage to him, advantage to you. TwinBee picks a target and waits for you to commit.",
+	"Half-health is the line for most bosses. The Hollow King's line is forty percent and he hits it dramatically. Wolves at his flanks, attacks now reckless. TwinBee respects the choreography.",

+	"The forest used to be a forest. That sentence is doing more work than it looks like it's doing. Something was let in — not summoned, not invaded, let in — and the forest has been a different kind of forest ever since. TwinBee has theories about who did the letting in. None of the theories are reassuring.",
+	"The Hollow King wasn't always hollow. He was a guardian once, the kind of guardian a forest gets when the forest is doing well. Then the forest started to do less well, and the guardian held on past the point where holding on was the kind thing to do. TwinBee finds the arc tragic and is not interested in absolving the outcome.",
+	"The bandits in the woods aren't local. They came from somewhere else, found the forest in its current state, and decided the cover was worth the risk. TwinBee notes their cookfires are recent and their numbers are growing. Someone is recruiting.",
+	"Owlbears shouldn't pack-hunt. These do. TwinBee has logged three separate engagements where two owlbears coordinated in a way that felt taught. Something in the corruption is rewriting their behavior. TwinBee doesn't like the implication.",
+	"The bioluminescent fungi are not native. They arrived with the corruption and they are part of the corruption — they fluoresce on a frequency that does something to the mood-banding of anyone who sleeps near them too long. TwinBee suggests resting somewhere darker if a long rest is on the schedule.",
+	"The Hollow Crown — the one the Hollow King wears, the one that drops if you beat him — is not the source of the corruption. It is a symptom. The source is older and is not in this zone. TwinBee won't say more, partly because TwinBee doesn't fully know.",
+	"There used to be a road through this forest. The road is still here. Nobody uses the road. TwinBee finds the road instructive — it goes exactly where it always went, but the going-where part stopped working when the forest stopped behaving like a forest.",
