agra 59f0aa7716 std: restructure — std/ modules, namespace tail, std/xml.sx
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.

// Two modules that each export a top-level `parse` — `std.cli.parse`
// (3-param subcommand dispatch) and `std.json.parse` (2-param document
// reader) — imported into ONE program under DISTINCT namespaces, with
// BOTH `parse`s actually called.
//
// Regression (issue 0100): same-name cross-module functions collided in
// the bare-name function table during IR lowering. Lowering re-resolved a
// call by SHORT name, so importing both modules and calling one bound the
// wrong-arity same-named function and tripped `lazyLowerFunction`'s
// param-count assert (panic). The fix resolves each `pkg.parse(...)` to a
// UNIQUE module-qualified FuncId, so `cli.parse` and `json.parse` are
// independent identities.
#import "modules/std.sx";
#import "modules/std/mem.sx"; // `Allocator` is non-transitive: name it, import it.
// `cli` is imported BOTH flat (so its types — `FlagSpec` / `Command` / `Diag` —
// are bare-visible) AND namespaced (so the same-name `cli.parse` stays a
// distinct qualified identity from `json.parse`). Post-E1 a bare reference to a
// namespaced-ONLY type is a "not visible" error, so the flat import is what makes
// the bare type names below resolve; `json` stays namespaced-only (its `Value`
// reaches `main` only as `json.parse`'s return type, resolved in `json.sx`'s own
// context).
