Adds opcode 112 (OP_PERFORM / IO suspension) to lib/vm.sx's vm-step
dispatch. The native sx_vm.ml already has this opcode — this brings
the SX spec into alignment.
Full VM transpilation deferred to Step 6 (define-record-type): the
dict-based state in vm.sx maps to get_val/sx_dict_set_b calls which
are ~5x slower than native record/array access in the hot loop.
define-record-type will let vm.sx use typed records that the
transpiler maps to OCaml records natively.
2598/2598 tests passing.

The SX-level VM couldn't find for-each/map/etc. because they're CEK
special forms, not primitives in the JS host. Added vm-resolve-ho-form
which creates wrapper functions that dispatch callbacks through
vm-call-external (handling VmClosure callbacks correctly).
Also fixed vm-call dispatch order: Lambda/Component checked before
generic callable? to avoid calling SX Lambdas as JS functions.
JS full: 1585/1585 (was 1582/3 failed). All 3 pre-existing failures fixed.

Registering map/for-each/reduce as PRIMITIVES caused the compiler to
emit CALL_PRIM for them everywhere. The OCaml VM's call-primitive
can't invoke VM closures, causing "Undefined symbol: resource" crashes.
Revert vm.sx to original CALL_PRIM handler. Remove map/for-each/reduce
from JS PRIMITIVES so compiler emits OP_CALL instead (handled by
vm-call which dispatches correctly).
3 JS VM tests remain failing (VM closure interop) but production is stable.

Handle for-each/map/reduce in VM's CALL_PRIM handler instead of JS
primitives. VM closures are called via vm-call-closure (fresh VM,
shared upvalue cells). Native callables dispatch directly.
Named let doesn't work inside vm-step context — use explicit define
+ recursion for reduce loop.
JS tests: 1585/1585 (0 failures)

spec/ now contains only the language definition (5 files):
evaluator.sx, parser.sx, primitives.sx, render.sx, special-forms.sx
lib/ contains code written IN the language (8 files):
stdlib.sx, types.sx, freeze.sx, content.sx,
bytecode.sx, compiler.sx, vm.sx, callcc.sx
Test files follow source: spec/tests/ for core language tests,
lib/tests/ for library tests (continuations, freeze, types, vm).
Updated all consumers:
- JS/Python/OCaml bootstrappers: added lib/ to source search paths
- OCaml bridge: spec_dir for parser/render, lib_dir for compiler/freeze
- JS test runner: scans spec/tests/ (always) + lib/tests/ (--full)
- OCaml test runner: scans spec/tests/, lib tests via explicit request
- Docker dev mounts: added ./lib:/app/lib:ro
Tests: 1041 JS standard, 1322 JS full, 1101 OCaml — all pass
