0.1.13 | Fix for PEAK update

Player.EmptySlot and PhotonNetwork.InstantiateItemRoom each gained an
optional parameter, which compiles fine but left the previous build
calling signatures that no longer exist. The InstantiateItemRoom throw
escaped the BagsForEveryone postfix and took down every
SingleItemSpawner in the level, which is why backpacks and BingBong
stopped spawning and campfires no longer advanced the biome.

Also hardens that postfix so a future API change costs the extra bags
and nothing else, registers them with the spawner's SpawnedItemTracker,
and stops the Open Backpack keybind from opening the wheel while the
backpack is held in hand.

 - Open the passport when pressing the "Open Passport" keybind (default: P)
 - Removed a leftover debug keybind on the BingBong module that was also bound to P and would have fired alongside the new passport keybind.

+# v0.1.13 | Fix for PEAK update
+
+- Rebuilt against the September PEAK update. Two game methods gained an optional parameter, which compiles fine but leaves an older build calling a signature that no longer exists, so both threw a MissingMethodException at runtime:
+  - `Player.EmptySlot(slot)` became `EmptySlot(slot, bool andBroadcast = true)`. This killed the whole "Toggle Bugle" keybind (default: V) — both giving the Bugle and swapping it for the Megaphone.
+  - `PhotonNetwork.InstantiateItemRoom(name, position, rotation)` gained a fourth `bool warnIfNotHost = true`. This one threw inside the Bags for Everyone postfix on `SingleItemSpawner.TrySpawnItems`, and because a throwing postfix propagates out of the method it patched, it took down every `SingleItemSpawner` in the level rather than just the backpack one. Backpacks and BingBong stopped spawning, and lighting a campfire no longer advanced the biome: the spawn loop runs inside `MapHandler`'s transition coroutine, so the throw killed that coroutine and the campfire items, day/night blend, biome title and fog reveal all silently never happened.
+- Removed the manual `RPCRemoveItemFromSlot` call the Bugle keybind made right after `EmptySlot`. `EmptySlot` already forwards the removal to the host itself, so the extra call only logged "Only Master Client can remove items!" on every press for anyone who wasn't hosting.
+- The "Open Backpack" keybind (default: B) no longer opens the wheel while the backpack is held in your hands. The wheel pulls items out of the backpack's on-back visuals, which the game deactivates while the backpack is in hand, so anything taken out was spawned into a disabled rig and disappeared. Hold-interacting the held backpack still opens it the normal way.
+- Hardened the Bags for Everyone patch. Its master-client and spawner-name checks now run in the postfix itself instead of inside the method that spawns the bags, and the spawn is wrapped in a try/catch. Because Mono resolves a method's call targets when it JITs that method, a changed game API used to throw before any of those checks could run, taking down every `SingleItemSpawner` in the level — which is what stopped campfires from advancing the biome in 0.1.12. A failure now costs the extra bags and nothing else.
+- The extra backpacks are registered with the spawner's `SpawnedItemTracker`, so a quicksave records them instead of restoring only the vanilla one, and the patch no longer adds a fresh batch on top every time a run is loaded from a save.
