EventLoop::new() from cargo test worker threads).

0.5.0 + glow 0.17.0 + raw-window-handle 0.6.2 + scopeguard 1.2.0 +
winit defaults). Pinned to versions resolved in /tmp/skia-glow-probe.
- .github/workflows/rust-check.yml: install Linux GL prereqs (xvfb,
mesa, libxkbcommon, libwayland) and add a P0-probe-gate step running
cargo test --ignored on each OS (Linux through xvfb-run; Windows
early-returns per spec §8.2 WINDOWS_GPU_DEFERRED_NO_RUNNER).
All three artefacts are TRANSIENT — reverted in a follow-up cleanup
commit after CI is green and the loader-compat notes commit lands.
Task 1 owns the permanent integration.

Previous version did `require('undici')` inside a try/catch on the
theory that would let it run on both CJS and ESM. In Vite/Nitro's dev
path the helper loads as an ESM module, where `require` is undefined —
the call threw `ReferenceError: require is not defined`, the catch
block silenced it, `configured=true` still got flipped, and every
subsequent call short-circuited. Net effect: the proxy was never
installed in the very dev environment the fix was meant to repair, so
image-search kept ECONNREFUSED-ing on Openverse + Wikimedia and
landing zero filled placeholders.
Switch to a static `import { setGlobalDispatcher, EnvHttpProxyAgent }
from 'undici'`. undici is a transitive dep of h3 in this workspace
(verified resolved in node_modules), and it's also the package Node 18+
uses internally for fetch — pinning it as a direct dep on apps/web
makes the resolution intentional rather than reliant on the h3 chain.
Also swapped the hand-rolled ProxyAgent for undici's built-in
`EnvHttpProxyAgent`: it reads HTTPS_PROXY / HTTP_PROXY / NO_PROXY
itself (case-insensitive) and applies the no-proxy bypass list, which
saves us from re-implementing those rules.
Verified with both `bun -e` (workspace deps) AND a direct ESM Node
context: with HTTPS_PROXY set, `fetch(api.openverse.org/...)` now
returns 240 results for "salmon sushi" instead of the earlier
ECONNREFUSED. The "configured" guard still makes calls idempotent so
multiple endpoints can opt in without coordinating.
Root cause for all-blank-placeholders on the food-app brief: Node's
native fetch (used by the Nitro dev server's image-search endpoint)
ignores the system proxy by default. On machines that route outbound
HTTPS through a local proxy (clash / mihomo / corporate gateway —
mine sits at 127.0.0.1:7897), every Openverse + Wikimedia call from
the server silently ECONNREFUSEDs. The endpoint's catch block returns
`null` for Openverse → falls back to Wikimedia → that ECONNREFUSEDs
too → returns `[]`. Browser shows zero filled images.
Direct curl from the same machine uses HTTPS_PROXY automatically, which
is why a manual API check (e.g. `curl https://api.openverse.org/...`)
returned 240 results for "salmon sushi" while
`/api/ai/image-search?query=salmon%20sushi` returned `{results:[]}`.
`apps/web/server/utils/proxy-dispatcher.ts::configureProxyDispatcher`:
- Reads HTTPS_PROXY / https_proxy / HTTP_PROXY / http_proxy.
- If set, installs `undici.ProxyAgent` as the global fetch dispatcher
via `setGlobalDispatcher`. From that point on every server-side
`fetch()` routes through the proxy.
- Idempotent — multiple endpoints can call it without re-installing.
- No-op when no proxy env var is present (production / CI).
- Dynamic `require('undici')` so a build target that strips undici
doesn't crash at import time.
Wired into `image-search.ts` at module top so the dispatcher is
configured before the first request lands. Other endpoints making
external fetches can opt in with the same single-line call.
Verified standalone via Bun: with the helper in place,
`fetch('https://api.openverse.org/v1/images/?q=salmon+sushi')` returns
240 results. The dev server itself needs a restart to pick up the
server-side change (Vite server-code HMR doesn't re-evaluate Nitro
modules).
