f2067848a7
Vendored 5.4.7 core+stdlib under lib/lua (mains excluded), LUA_32BITS baked into luaconf.h so the VM and embedders share one ABI. LuaHost spike behind WADA_LUA_SPIKE: PSRAM-only allocator with a hard 256KB cap, io/os-free sandbox, instruction-budget hook. Measured on the T-Deck: flash +96KB, state+libs 7.5KB/2ms, hostile while-true contained in 30ms, zero leak. Inert (byte-identical build) when the flag is off.
