bend: dual-port worker (8320 wire + 8321 http) — playground onramp
Each gpu-worker.lsp now listens on both wire-TCP (existing :8320) and
HTTP/1.1+CORS (new :8321), sharing one handle-request dispatcher. Lets
a tab on https://lumbda.com/playground/ POST to its own machine via
http://localhost:8321/ — browsers permit localhost from HTTPS origins
without TLS, so no proxy, no cert, no fox-owned infra required for the
decentralized run-your-own-bend story.

main() forks at startup: child runs http-run-loop on :8321, parent
keeps existing run-loop on :8320. Adding a new op-head to handle-request
exposes it over both transports automatically. Binary modes
(BSHK/BCGB/BSCP/BSRT/BSB3) stay wire-only — they exist for native
callers who already cache the binary locally; browser callers send
S-expression recipes the worker dispatches the same way.

Two latent defects fixed to make CPU-only and Python-tier hosts work:
- vram-used-mib now file-exists? guards /usr/bin/nvidia-smi. Python
  tier's spawn-process-stdio raises FileNotFoundError on missing
  binary, not returning #f as the prior code expected, which crashed
  every worker on a CPU-only laptop.
- fork-self return discriminated via (number? pid) not (eq? pid 0).
  Python tier's (eq? 0 #f) returns #t because == conflates int 0
  with bool False; pre-existing run-loop has the same risk but
  C/asm tier (identity eq?) masks it for the production case.

Phase 2 (server-side factory ops: compile uploaded .lsp recipes into
.bin before bending — the foxhop champion-circuit workflow) deferred
until authentication lands; today a worker on the public internet
would let any caller occupy our GPU.

Operational Caddy + DNS proposals in plans/bend-http-deploy.md cover
the personal-remote-access endpoint chain (proxy.unturf.com edge →
ai.foxhop.net Caddy → 3090-ai:8321) gated by trusted-IP allowlist —
applied separately.

Also codifies the playground "CSS Grid only, never flexbox" rule in
CLAUDE.md: all www/ and wasm/ stylesheets are already grid-only;
documenting the invariant so future edits don't drift.

Tests: smoke-bend-http.sh — (ping)→(ok pong), unknown-op fallback,
OPTIONS CORS preflight — all PASS. Wire path unchanged, verified
round-trip via 8-digit-prefix framing.
