Migrate Atomic methods from seq_cst-only to the explicit ordering surface now that comptime value params work on generic-struct methods (workers3c4305f/d7a6857/d95ba0a): - atomic.sx: load/store take a comptime $o: Ordering (explicit, Rust-style; no default, matching design 4.6). a.load(.acquire) -> 'load atomic .. acquire'. - call.zig: atomicOrderingFromNode resolves a comptime-bound ordering identifier via comptimeIntNamed (+ atomicOrderingFromTag); documents the sx-Ordering <-> IR-AtomicOrdering declaration-order invariant. The per-op validity guard fires through the method path (a.load(.release) is a compile error). - 1700 migrated to explicit orderings (output unchanged 7/42/43). Suite green (715/0).
