Constant LSHAPE_SOURCES 

pub const LSHAPE_SOURCES: &[(&str, &str)];

Embedded Lua source files. Key is the require path (e.g. "lshape" → lua/lshape/init.lua), value is the file contents.

Kept pub so downstream crates can embed the same sources (e.g. to inject them into a non-mlua Lua VM or to hash them for drift checks).
