pub const LIBRARY_VERSION: &str = "27";Expand description
Expected library version. Must match FCALL ff_version 0 return.
Single source of truth is lua/version.lua. The gen script
extracts the return 'X' literal and writes it to
flowfabric_lua_version. Bump lua/version.lua whenever any Lua
function’s KEYS or ARGV arity changes, or a new function is added.
