c5cc022aa2 Add SDL2+OpenGL ES 2 renderer backend for Emscripten/WebGL
Implements Phase 1 of renderer abstraction plan:
- SDL2Types.h: SFML-compatible type stubs in sf:: namespace
- SDL2Renderer.h/cpp: OpenGL ES 2 rendering implementation
- EmscriptenStubs.cpp: Stubs for missing POSIX functions (wait3, wait4, wcsftime)

Build system changes:
- Add MCRF_SDL2 compile-time backend selection
- Add Emscripten SDL2 link options (-sUSE_SDL=2, -sFULL_ES2=1)
- Fix LONG_BIT mismatch for Emscripten in pyport.h

Code changes for SDL2/headless compatibility:
- Guard ImGui includes with !MCRF_HEADLESS && !MCRF_SDL2
- Defer GL shader initialization until after context creation

Current status: Python runs in browser, rendering WIP (canvas sizing issues)

Build commands:
  emcmake cmake -DMCRF_SDL2=ON -B build-emscripten
  emmake make -C build-emscripten

7621ae35bb Add MCRF_HEADLESS compile-time build option for #158
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

Addresses #158

87444c2fd0 HeightMap: add GRID_MAX limit and input validation
Fixes potential integer overflow and invalid input issues:

- Add GRID_MAX constant (8192) to Common.h for global use
- Validate HeightMap dimensions against GRID_MAX to prevent
  integer overflow in w*h calculations (65536*65536 = 0)
- Add min > max validation for clamp() and normalize()
- Add unit tests for all new validation cases

07b597d6f2 Refactor: Python 3.12, build libtcod & SFML from source. Cmake build. Directory cleanup
directories needed:
* build - for cmake output
* deps - stuff needed to compile McRogueface (headers)
	libtcod -> ../modules/libtcod/src/libtcod
	sfml -> ../modules/SFML/include/SFML
	python -> ../modules/cpython/Include
* lib - stuff needed to link McRogueFace (shared objects); also required at runtime
	libtcod -> `../modules/libtcod/buildsys/autotools/.libs/libtcod.so.1.0.24`
	sfml -> `../modules/SFML/build/lib/*`
	python -> `../modules/cpython/libpython3.12.so`; standard lib at ../modules/cpython/build/lib.linux-x86_64-3.12 & ../modules/cpython/Lib

You can get dependencies by:
 - Build from source (i.e. all submodules)
 - Go download them from each project's website
 - install packages from your distro and symlink them to deps/lib directories
