WASM kernel fixes: parse, env sync, iterative CEK, click delegation

Browse Source

Browser kernel:
- Add `parse` native fn (matches server: unwrap single, list for multiple)
- Restore env==global_env guard on _env_bind_hook (let bindings must not
  leak to _vm_globals — caused JIT CSSX "Not callable: nil" errors)
- Add _env_bind_hook call in env_set_id so set! mutations sync to VM globals
- Fire _vm_global_set_hook from OP_DEFINE so VM defines sync back to CEK env

CEK evaluator:
- Replace recursive cek_run with iterative while loop using sx_truthy
  (previous attempt used strict Bool true matching, broke in wasm_of_ocaml)
- Remove dead cek_run_iterative function

Web modules:
- Remove find-matching-route and parse-route-pattern stubs from
  boot-helpers.sx that shadowed real implementations from router.sx
- Sync boot-helpers.sx to dist/static dirs for bytecode compilation

Platform (sx-platform.js):
- Set data-sx-ready attribute after boot completes (was only in boot-init
  which sx-platform.js doesn't call — it steps through boot manually)
- Add document-level click delegation for a[sx-get] links as workaround
  for bytecoded bind-event not attaching per-element listeners (VM closure
  issue under investigation — bind-event runs but dom-add-listener calls
  don't result in addEventListener)

Tests:
- New test_kernel.js: 24 tests covering env sync, parse, route matching,
  host FFI/preventDefault, deep recursion
- New navigation test: "sx-get link fetches SX not HTML and preserves layout"
  (currently catches layout breakage after SPA swap — known issue)

Known remaining issues:
- JIT CSSX failures: closure-captured variables resolve to nil in VM bytecode
- SPA content swap via execute-request breaks page layout
- Bytecoded bind-event doesn't attach per-element addEventListener (root
  cause unknown — when listen-target guard appears to block despite element
  being valid)
