"""Build hatchsys.ling (everything) and hatchmini.ling (the small LCD build) from the parts in src/

The Ling JIT does not see top-level bindings of `use`d modules, so the program has to be one file.
This script concatenates src/*.ling in name order and drops the generated glyph block
(DAEMON / CHESILIN outlines, kept in hatchmem.ling by tools/gen_glyphs.py) in right after 10_head.ling.
