Add a standalone CMake build for luac that produces bytecode compatible with EdgeTX's 32-bit Lua 5.3 (float numbers, int integers). This lets users compile scripts on their host machine or in CI without needing Companion, which is especially useful for memory-constrained radios where on-radio compilation may fail due to insufficient RAM. Build: cmake -S radio/src/thirdparty/Lua -B build-luac cmake --build build-luac Usage: edgetx-luac -s -o script.luac script.lua Changes: - New radio/src/thirdparty/Lua/CMakeLists.txt for host build - luaconf.h: guard EdgeTX debug.h behind LUA_HOST_BUILD - luac.c: remove dangling lnodemcu.h include, guard alloca.h, fix use of uninitialized filelist[] (should be argv[]) Ref: #7251
Build edgetx-luac as a WebAssembly module so users can compile Lua scripts to EdgeTX bytecode directly in their browser with no server. - luac_wasm.c: thin C wrapper exposing compile/malloc/free exports - build-wasm.sh: builds with wasi-sdk (-Os, gc-sections, sjlj) - wasm/index.html: self-contained web app with editor, drag-and-drop, file upload, and .luac download (EdgeTX-branded) Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

This PR adds a standalone Lua compiler that can be used to pre-compile Lua scripts to save memory when running scripts on constrained devices (see #7251).
