Major milestone for issue #158 (Emscripten/WebAssembly build target): - Python 3.14 successfully initializes and runs in WASM - mcrfpy module loads and works correctly - Game scripts execute with full level generation - Entities (boulders, rats, cyclops, spawn points) placed correctly Key changes: - CMakeLists.txt: Add 2MB stack, Emscripten link options, preload files - platform.h: Add WASM-specific implementations for executable paths - HeadlessTypes.h: Make Texture/Font/Sound stubs return success - CommandLineParser.cpp: Guard filesystem operations for WASM - McRFPy_API.cpp: Add WASM path configuration, debug output - game.py: Make 'code' module import optional (not available in WASM) - wasm_stdlib/: Add minimal Python stdlib for WASM (~4MB) Build with: emmake make (from build-emscripten/) Test with: node mcrogueface.js Next steps: - Integrate VRSFML for actual WebGL rendering - Create HTML page to host WASM build - Test in actual browsers Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>

"""Python 'bz2_codec' Codec - bz2 compression encoding.

This codec de/encodes from bytes to bytes and is therefore usable with

Adapted by Raymond Hettinger from zlib_codec.py which was written
