* Export MultiplayerExt symbols accessed from isle executable
When lego1 is built as a shared library (DLL), symbols used by the isle
executable through the Extension<T>::Call() template need to be exported.
Add LEGO1_EXPORT to MultiplayerExt::enabled and MultiplayerExt::CheckRejected()
which are referenced from isleapp.cpp via the template instantiation.

* Use inline const instead of constexpr for extension function pointers
constexpr cannot be used with dllimport function addresses since they
are resolved at load time through the IAT, not at compile time. Change
to inline const which preserves the single-definition semantics (via
inline) while allowing runtime initialization of the function pointers.

* Fix multiplayer extension link errors across DLL boundary
When lego1 is a shared library, Extension<T>::Call() instantiated from
isle.exe references MultiplayerExt::enabled and CheckRejected() which
are not exported. Instead of exporting internal symbols (which also
breaks constexpr with dllimport), add an exported IsMultiplayerRejected()
wrapper that keeps the Extension<T>::Call() instantiation inside lego1.

* Guard IsMultiplayerRejected with EXTENSIONS ifdef
extensions.cpp is only compiled when ISLE_EXTENSIONS is ON, so the
wrapper function and its call site need #ifdef EXTENSIONS guards for
targets like x86 MSVC where extensions are disabled.

* Move IsMultiplayerRejected definition to multiplayer.cpp
The function is declared in multiplayer.h and belongs with the rest of
the multiplayer extension code, not in the general extensions.cpp file.

- Remove hardcoded multiplayer config from emscripten config.cpp
- Add relay HTTP endpoints for room preview (GET) and creation (POST)
with capacity check, CORS headers, and configurable max players
- Add WebSocket rejection detection (room full/503) via onclose flag
- Add CheckRejected extension call in IsleApp::Tick for clean shutdown
through SDL_APP_SUCCESS path instead of calling exit()
- Set Module._exitCode in JS for sessionStorage-based toast after reload
Read "multiplayer:room" from INI options (default "default") and use it
in Connect() instead of a hardcoded string. Return early if room is blank,
matching the relay URL check. Rename p_mgr to p_networkManager for consistency.
Move world state synchronization logic (snapshots, events, entity
mutation routing) into a dedicated WorldStateSync class, reducing
NetworkManager from ~790 to ~420 lines.
Revert plant/building manager globals back to private class statics
(matching master) and use friend declarations for extension access.
Move CreateCharacterClone out of LegoCharacterManager into a new
CharacterCloner class in the multiplayer extension.
Add serialization framework using C++ templates and table-driven lookup
to sync plant and building state between players. Includes world snapshot
routing to requesting peer, relay server Docker support, and fixes for
building color sync, ride vehicle visibility, and ARM compilation.
- Replace manual vector math in UpdateTransform with CalcLocalTransform and vec.h macros (LERP3, SET3, MV3, DISTSQRD3, ZEROVEC3)
- Remove all SDL_Log debug logging from multiplayer code
- Strip extraneous comments that restate the code
- Extract CreateAndSpawnPlayer helper to consolidate repeated spawn pattern
- Simplify UpdateVehicleState control flow
- Remove unused includes (SDL_log.h, mxgeometry/mxmatrix.h)
- WebSocket relay server (Cloudflare Worker + Durable Object)
- Remote player character cloning with walk/idle/ride animations
- Vehicle support for remote players
- INI config for relay URL
- Extension hook for world transition ROI management
