When HTTP_PROXY/HTTPS_PROXY env vars are set, @npmcli/arborist's
dependency chain (@npmcli/agent) creates a proxy agent whose .proxy
getter returns { url: URL_object }. Bun's node:http polyfill reads
this and passes it to native fetch(), which expects proxy.url to be a
string, not a URL instance. This triggers:
fetch() proxy.url must be a non-empty string
Pass agent:false to Arborist to skip @npmcli/agent entirely. Bun's
native fetch layer then handles proxy via its own env var fallback
(HTTP_PROXY/HTTPS_PROXY), which works correctly with string URLs.

opencode\packages\shared\src\npm.ts can also apply this fix because it uses new Arborist and can cause same issue when run "bun run dev" |

The existing patch (anomalyco#23460, commit e539efe) fixes @npmcli/agent's URL-object crash, but the agent itself still hangs on CONNECT through corporate proxies — request never reaches Bun's native fetch layer, times out after 70s with "Was there a typo in the url or port?". Pass agent:false to Arborist on Bun runtime, ports the fix from upstream PR anomalyco#21832 to our fork's location (packages/core/src/npm.ts instead of packages/opencode/src/npm/index.ts). Bun's FetchTasklet then handles HTTP_PROXY/HTTPS_PROXY/NO_PROXY natively, which is verified working via models.dev fetch in the same session. Node.js path is unaffected (typeof Bun guard).

What does this PR do?
When
HTTP_PROXY/HTTPS_PROXYenv vars are set, plugin installation via npm crashes withfetch() proxy.url must be a non-empty string.The cause is a type mismatch between
@npmcli/agentand Bun'snode:httppolyfill. Arborist's dependency chain uses@npmcli/agentwhich reads proxy env vars and exposes.proxyas{ url: URL_object }(a JSURLinstance, not a string). Bun'snode:httppolyfill (_http_client.ts) readsagent.proxyand passes it to nativefetch(). Bun's native fetch validates thatproxy.urlis a string, but aURLobject fails this check.The fix: pass
agent: falsetoArboriston Bun runtime. This skips@npmcli/agententirely. Bun'sFetchTaskletthen handles proxy itself by readingHTTP_PROXY/HTTPS_PROXYfromprocess.envas plain strings, which works correctly. The option is only applied whentypeof Bun !== "undefined", so Node.js is unaffected.How did you verify your code works?
