This commit enables McRogueFace to compile without SFML dependencies
when built with -DMCRF_HEADLESS, a prerequisite for Emscripten/WebAssembly
support.
Changes:
- Add src/platform/HeadlessTypes.h (~900 lines of SFML type stubs)
- Consolidate all SFML includes through src/Common.h (15 files fixed)
- Wrap ImGui-SFML with #ifndef MCRF_HEADLESS guards
- Disable debug console/explorer in headless builds
- Add comprehensive research document: docs/EMSCRIPTEN_RESEARCH.md
The headless build compiles successfully but uses stub implementations
that return failure/no-op. This proves the abstraction boundary is clean
and enables future work on alternative backends (VRSFML, Emscripten).
What still works in headless mode:
- Python interpreter and script execution
- libtcod integrations (pathfinding, FOV, noise, BSP, heightmaps)
- Timer system and scene management
- All game logic and data structures
Build commands:
Normal: make
Headless: cmake .. -DCMAKE_CXX_FLAGS="-DMCRF_HEADLESS" && make

New Features:
- Scene Explorer window (F4) displays hierarchical tree of all scenes
- Shows UIDrawable hierarchy with type, name, and visibility status
- Click scene name to switch active scene
- Double-click drawables to toggle visibility
- Displays Python repr() for cached objects, enabling custom class debugging
- Entity display within Grid nodes
Bug Fixes:
- Fix PythonObjectCache re-registration: when retrieving objects from
collections, newly created Python wrappers are now re-registered in
the cache. Previously, inline-created objects (e.g.,
scene.children.append(Frame(...))) would lose their cache entry when
the temporary Python object was GC'd, causing repeated wrapper
allocation on each access.
- Fix console focus stealing: removed aggressive focus reclaim that
caused title bar flashing when clicking in Scene Explorer
Infrastructure:
- Add GameEngine::getSceneNames() to expose scene list for explorer
- Scene Explorer uses same enabled flag as console (ImGuiConsole::isEnabled())

Integrates Dear ImGui for an in-game debug console that replaces the
blocking Python REPL. Press ~ (grave/tilde) to toggle the console.
Features:
- Python code execution without blocking the game loop
- Output capture with color coding (yellow=input, red=errors, gray=output)
- Expression results show repr() automatically
- Command history navigation with up/down arrows
- Word wrapping for long output lines
- Auto-scroll that doesn't fight manual scrolling
- mcrfpy.setDevConsole(bool) API to disable for shipping
Technical changes:
- Update imgui submodule to v1.89.9 (stable)
- Update imgui-sfml submodule to 2.6.x branch (SFML 2.x compatible)
- Add ImGui sources to CMakeLists.txt with OpenGL dependency
- Integrate ImGui lifecycle into GameEngine
- Add ImGuiConsole class for console overlay
