Advances p3-10a. Moving a stack onto a wild-lair tile now opens a small
CanvasLayer mode picker (modeled on promotion_picker.tscn) before combat:
Assault (enabled), Raid (disabled — p3-10c), Siege (disabled — p3-10b). The
picker emits mode_chosen(mode) / cancelled(); world_map_combat.initiate_lair_combat
opens it and routes the Assault branch through _begin_lair_assault → the existing
p0-17 show_lair_preview → _handle_lair_clear path (per p3-10a, "the existing path
IS the assault"), so the working lair-clear flow is not regressed.
Scope note: Assault routes through the live p0-17 flow, NOT GdLair.assault()
(api-gdext/src/lair.rs) — that bridge is the 7-arg JSON marshaller and would
require building attacker/defender JSON + loading tier_NN.json + applying
loot/survivor/clear outcomes in GDScript, duplicating the working path. The
p3-10a bullet therefore stays ◐ (bridge not exercised end-to-end; no picker
proof screenshot yet).
GUT: tests/unit/test_lair_mode_picker.gd 5/5 green on apricot headless
(only-Assault-enabled, Assault emits mode_chosen("assault"), Cancel emits
cancelled() and no mode, disabled Raid/Siege never emit via the in-handler
guard, target label resolves the lair name). All-Dwarf vocab keys
(lair_picker_*, lair_mode_*) authored in vocabulary.json.
