`compile_error(msg)` raises a build-time diagnostic at the call site with `msg` as the error text. The arg must be a string literal — runtime expressions can't be reported as compile errors. Used by builder fns to reject malformed pack shapes / arg combinations cleanly instead of silently emitting wrong code. Today: `unresolved 'compile_error'`. Expected (post-fix): focused diagnostic with the literal message at the call site's span. The next commit adds the lowering arm.
