allocators/fs/process/socket/log/trace/test move under modules/std/ (allocators.sx becomes std/mem.sx; the Allocator protocol moves into the std.sx prelude, impls stay in mem.sx). New std/xml.sx holds xml_escape as xml.escape. std.sx gains the carried namespace tail — flat-importing std.sx now also provides mem./xml./log. — with the remaining modules (fs/process/socket/json/cli/hash/test) deferred from the tail until the global last-wins maps are fully own-wins (pulling them into every closure collides bare names corpus-wide; they stay direct imports: modules/std/fs.sx etc.). log.sx's internal emit renamed log_emit (it clobbered consumer fns named emit program-wide). bundle.sx uses xml.escape via the carried alias. Consumer import paths swept mechanically; .ir snapshots recaptured for the larger std closure. m3te + game build unchanged.
