IO Suspension:
- Set _cek_io_resolver in test runner to handle perform/wait/fetch
- io-sleep/io-wait: instant resume (no real delay in tests)
- io-fetch: returns mock {ok:true, status:200, json:{foo:1}} response
- io-wait-for/io-settle: instant resume
- Fixes ~30 tests that were failing with VmSuspended or timeouts
Append command:
- hs-append (pure): string concat or list append
- hs-append! (effectful): DOM insertAdjacentHTML
- Compiler emits set! wrapper for variable targets
Mock DOM:
- dom_stringify handles List → comma-separated string
