playground+repl: bend dispatch from WASM + 1.33 zoom + free-form runner
bend!-call from the WAT tier
  - New WAT import: (import "env" "bend_call"). The host loader supplies
    a sync XMLHttpRequest that POSTs the payload to a configured URL
    (workers only — sync XHR isn't allowed on main thread).
  - New primitive (bend!-call "<payload>") returns the response as a
    lumbda string. Works in playground and REPL once the bend URL is
    saved in the new top bar.
  - bendUrl persists in plain localStorage (not encrypted — it's a
    server address, not a secret).
  - Tests stub the import with a no-op so unit / integration / functional
    suites keep instantiating cleanly.

Playground + REPL zoom 133% by default
  - html { zoom: 1.33 } so the styleguide sizes read comfortably without
    requiring browser-level zoom.

Free-form default = cross-tier assertion runner in Lisp
  - The default editor content for "free form" is now a small assertion
    framework matching tests/functional.lsp's PASS/FAIL convention. A
    starter the user can extend, runs identically on the three tiers.

C tier + Python tier (bend) are wired through the runner stub; full
bend integration in those tiers comes next once their loaders learn
about setBendUrl.
