Move OS / ARCH / POINTER_SIZE + the OperatingSystem / Architecture enums out of build.sx into a new std/target.sx that imports NOTHING, so low-level code can name the target enum types without dragging the build/std barrel (build.sx transitively pulls std + compiler + bundle, ~16k lines of IR). build.sx flat-imports target.sx so the decls stay registered in the standard import graph (build.sx is reachable from std.sx — dropping it would shift every std program's type table). This is not a re-export: flat import only splices into build.sx's own scope. Consumers are unaffected — the compiler resolves OS / ARCH / POINTER_SIZE by name (comptime constants), so `inline if OS`/value reads need no import; a module that names the enum type imports target.sx. No behavior change (full suite green, 817/0); the enum types stay in the same import graph, so no .ir snapshot drift.

// src/imports.zig). NOTE: a top-level `inline if OS/ARCH/POINTER_SIZE`
|
|
// conditional is resolved by the compiler's flatten pre-pass and needs NO
|
|
// import at all (that is how std/net/epoll.sx selects its layout). Import this
|
|
// module only when you need the enum TYPE (`OperatingSystem` / `Architecture`)
|
|
// or a value in a non-`inline if` position.
|
|
//
|
|
// build.sx imports this (flat) so the decls stay registered in the standard
|
|
// import graph — NOT to re-export them (flat import doesn't propagate to a
|
|
// module's importers). Code that names the OperatingSystem / Architecture TYPE
|
|
// imports this module directly; OS / ARCH / POINTER_SIZE values and `inline if`
|
|
// conditions are resolved by the compiler by name and need no import.
