Add verbose_air.c/h implementing a human-readable AIR printer for debugging the C sema, ported from src/Air/print.zig. Types print as human-readable names (u32, *const u8, fn (...) noreturn) instead of raw IP indices. Add --verbose-air flag to zig0 CLI and a `zig build zig0` target for building the standalone executable. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
