71d1ac9ce4 Hyperscript examples: add Try it buttons, test stub VM continuation bug
- ~hyperscript/example component: shows "Try it" button with _= attr
  for all on-click examples, source pre wraps long lines
- Added CSS for .active/.light/.dark demo classes with !important
  to override Tailwind hover states
- Added #target div for the "put into" example
- Replaced broken examples (items, ~card, js-date-now) with
  self-contained ones that use available primitives
- Repeat example left in with note: continuation after loop pending
- New test suite io-suspension-continuation documenting the stub VM
  bug: outer do continuation lost after suspension/resume completes

33e8788781 Lambda→CEK dispatch: enable IO suspension through sx_call
Lambda calls in sx_call now go through the CEK machine instead of
returning a Thunk for the tree-walker trampoline. This lets perform/
IO suspension work everywhere — including hyperscript wait/bounce.

Key changes:
- sx_runtime: Lambda case calls _cek_eval_lambda_ref (forward ref)
- sx_vm: initializes ref with cek_step_loop + stub VM for suspension
- sx_apply_cek: VmSuspended → __vm_suspended marker dict (not exception)
- continue_with_call callable path: handles __vm_suspended with
  vm-resume-frame, matching the existing JIT Lambda pattern
- sx_render: let VmSuspended propagate through try_catch
- Remove invalid io-contract test (perform now suspends, not errors)

5f72801901 Step 3: IO registry — spec-level defio + io contract dispatch
Promotes defio from native OCaml special form to spec-level CEK
evaluator feature. The IO registry is now the contract layer between
evaluator and platform.

Evaluator additions (spec/evaluator.sx):
- *io-registry* mutable dict global (like *library-registry*)
- io-register!, io-registered?, io-lookup, io-names accessors
- defio-parse-kwargs! recursive keyword parser
- sf-defio processes (defio "name" :category :data :params (...) ...)
- "defio" dispatch in step-eval-list
- step-sf-io: the contract function — validates against registry,
  then delegates to perform for IO suspension
- "io" dispatch in step-eval-list

Native OCaml defio handlers removed from:
- sx_server.ml (~20 lines)
- sx_browser.ml (~20 lines)
- run_tests.ml (~18 lines)
All replaced with __io-registry alias to spec's *io-registry*.

IO accessor functions bound in run_tests.ml env so tests can
call io-registered?, io-lookup, io-names.

10 new tests (spec/tests/test-io-registry.sx):
- defio populates registry
- io-lookup returns spec with name/category/returns/doc
- io-registered?/io-names work correctly
- kwargs parsing (batchable, cacheable, params)
- io contract rejects unregistered ops
- io contract passes validation for registered ops

2608/2608 tests passing (+10 new).
