giles 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).
