🐛 reposition debug panel when Nisse info panel is open (#41)

Debug panel shifts below the Nisse info panel to avoid overlap.
repositionDebugPanel() is called on toggle, open, and close.

 ## [Unreleased]
 
+### Fixed
+- **Debug-Panel überlagert Nisse-Info-Panel** (Issue #41): F3-Debug-Panel weicht dynamisch aus — wenn das Nisse-Info-Panel offen ist, erscheint das Debug-Panel unterhalb davon statt darüber
+- **Stockpile-Overlay Transparenz** (Issue #39): `updateStaticPanelOpacity()` verwendete `setAlpha()` statt `setFillStyle()` — dadurch wurde die Opacity quadratisch statt linear angewendet; bei 100 % blieb das Panel sichtbar transparent
+- **Action Bar Transparenz** (Issue #40): Action Bar ignorierte `uiOpacity` komplett — Hintergrund war hardcoded auf 0.92; wird jetzt korrekt mit `uiOpacity` erstellt und per `updateStaticPanelOpacity()` live aktualisiert
+
+### Performance
+- **Event-queue timers** (Issue #36): crops, tree seedlings, and tile-recovery events now use a sorted priority queue with absolute `gameTime` timestamps instead of per-frame countdown iteration — O(due items) per tick instead of O(total items); `WorldState.gameTime` tracks the in-game clock; save migrated from v5 to v6
+
+### Added
+- **Action log in F3 debug panel** (Issue #37): last 15 actions dispatched through the adapter are shown in the F3 overlay under "Last Actions"; ring buffer maintained in `LocalAdapter`
+
 ### Fixed
 - **Y-based depth sorting** (Issue #31): trees, rocks, seedlings and buildings now use `tileY + 5` as depth instead of fixed values — objects lower on screen always render in front of objects above them, regardless of spawn order; build ghost moved to depth 1000
 - **Nisse always visible** (Issue #33): Nisse sprites fixed at depth 900, always rendered above world objects
