Brandon Lucas 67437b8273 feat: replace Cranelift JIT with C backend ...

Remove Cranelift JIT compiler and expose the existing C backend as the
compilation target. Generated C code can be compiled with GCC/Clang.

Changes:
- Remove cranelift-* dependencies from Cargo.toml
- Delete src/compiler.rs (565 lines of Cranelift code)
- Add compile_to_c() function with -o and --run flags
- Fix C backend name mangling (main -> main_lux) to avoid conflicts
- Update CLI help text and documentation

Usage:
  lux compile <file.lux>           # Output C to stdout
  lux compile <file.lux> -o out.c  # Write to file
  lux compile <file.lux> --run     # Compile and execute

C backend supports: functions, basic types, operators, if/then/else,
records, enums, Console.print. Future work: closures, lists, patterns.
