Addresses the Copilot review on #2099.
- `/api/fetch` used the bare global `fetch`. That route is the browser's only
way out to the network — the web client's `environment.fetch` is
`createRemoteFetch()`, which forwards OAuth discovery and token requests
there — so a corporate-proxy user could connect to a server but never
authorize against it, and the PR's "OAuth is proxied now" claim held for the
CLI and TUI but not for web. It now uses the same proxy-aware base fetch, with
an integration test driving a real forwarding proxy (confirmed failing without
the fix).
- `verify:bundle-externals` only recognized an inlining that produced a
`<pkg>-HASH.js` chunk. A *statically* imported package is folded into
`index.js` and emits no chunk, so it would have passed. Detection now keys off
esbuild's `// <path>` module banners, covering both shapes. Because that
depends on unminified output, a bundle with no banners now fails as such
rather than reporting clean — enabling `minify` cannot silently retire the
check. Tests cover the entry-inlined case, the same-prefix case
(`undici-types` must not read as `undici`), and the no-banner case.
- The pre-push pipeline summaries in AGENTS.md, README.md, and
.github/copilot-instructions.md still described `verify:build-gate → smoke`
and omitted the new gate.
