Add src/PazeE.los4/ — a pure C implementation of the PazeE compiler
that generates static Los4 ELF executables (x86-64, int 0x80 syscalls).
Core components:
- Lexer, preprocessor, recursive-descent parser, AST
- Tree-walking interpreter (paze run) with breakpoints
- x86-64 code generator (SysV AMD64 ABI)
- Los4 ELF writer (4 PH layout matching doomlauncher.elf, base 0x400000)
- Runtime library as raw machine code: printf, sprintf, puts, malloc,
memcpy, memset, strcmp, strlen, exit, etc.
Key fixes:
- Fix use-after-free: AST paze_str_t slices point into source buffer,
so free(src) is deferred until after interpreter/codegen completes
- printf/sprintf support %d/%i/%u/%x/%c/%s/%% with rel32 jumps
- External function calls resolved via runtime offset lookup
All 14 test cases pass for both paze run and paze build.
Also includes DebuggerVM.cs and Program.cs updates for the C# compiler.
