Lands the full VM/compiler-API arc on branch reify (701/0 both gates): - abi(.compiler) ABI replaces abi(.zig) extern compiler + the fake #library "compiler"; bodiless decl = compiler-API surface, bodied = user compiler-domain fn (lowered for VM eval, emit-skipped). - out is a plain sx fn (libc write) — the out builtin deleted; the VM handles it via host-FFI. trace_resolve + interp_print_frames ported. - 4B VM-native diagnostics: 1179/1180 render proper comptime type construction failed: under strict. - S5a: build_options/set_post_link_callback on abi(.compiler) with BuildConfig threaded into the VM (green intermediate). - 0522 fixed (describe(args: []Type)); regression 0638. Strict deletion-gate down to 4 compiler_call bails (1609/1614/1615/1616) + 1654 (legitimate unresolvable-symbol diagnostic).

// `cast(T) val` inside a conditional, evaluated by the IR interpreter

// (`i64`) as a `placeholder` IR op; the interpreter treats placeholders
