Sexp Module

The sexp subsystem provides:

• a fast S-expression tokenizer/parser/pretty-printer in Zig, and
• typed Zig models for KiCad formats (PCB, footprint, netlist, symbol, schematic, fp_lib_table), exposed to Python via the pyzig_sexp extension module.

Source-of-truth docs and code:

• src/faebryk/core/zig/README.md (high-level overview)
• src/faebryk/core/zig/src/sexp/* (tokenizer/AST/structure)
• src/faebryk/core/zig/src/python/sexp/sexp_py.zig (Python API + critical memory rules)
