sprint A cleanup: accessibility, signals, race, debris

G: large_text scales global theme font (14→20 at 1.4×) via new
GameState.get_font_scale + EventBus.settings_changed. reduce_motion
gates ResumeToast fade (HintOverlay already gated).

I: InspectTooltip long-press wired (500ms hold, 12px drift cancel,
tap-to-clear pin). Stale Phase 19 TODO replaced with accurate doc.

H: Pawn.arrived_at_destination now also emitted on
EventBus.pawn_arrived_at_destination; DirtinessSystem subscribes and
bumps indoor traffic dirt (BUMP_INDOOR_TRAFFIC = 0.2). Outdoor-tracked
bump needs Pawn.prev_tile — flagged for Phase 20.

P: CraftingProvider caches ingredient item ref on Job.ingredient_item;
JobRunner._tick_pickup validates is_instance_valid + not being_carried
before the tile scan, cancels cleanly if another pawn grabbed it.

J: rest_provider.gd deleted. Removed @onready + register call from
world.gd, ext_resource + node from world.tscn. Provider count comment
updated to 9.

M: DIRTY_THRESHOLD extracted — cleaning_provider and job_runner now
reference DirtinessSystem.DIRT_DIRTY_THRESHOLD.
