Erik 4a1c594887 docs(B.4b): design spec for outbound Use handler wiring ... Phase B.4b closes the M1-blocker discovered during the L.2g slice 1 visual test: the input dispatcher fires SelectDblLeft on click but GameWindow.OnInputAction has no case for any Select* / UseSelected action, so clicks silently die. Spec creates the minimum new structure to close the gap: - New static helper WorldPicker (BuildRay + Pick over WorldEntities) - Rename _selectedTargetGuid -> _selectedGuid on GameWindow (unifies combat + interaction selection per retail's single-target model) - Three switch cases (SelectLeft, SelectDblLeft, UseSelected) Two further L.2g handoff inaccuracies surfaced during exploration: WorldPicker and SelectionState do NOT exist in src/ (handoff and ISSUES #57 both claimed they did). BuildPickUp also doesn't exist; only BuildUse / BuildUseWithTarget / BuildTeleToLifestone are present. Spec accounts for the actual state and defers BuildPickUp + SelectionState class extraction. Visual verification scenario reuses the L.2g slice 1 reproducibility recipe: one Holtburg inn doorway log captures both L.2g + B.4b.
