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.
