What does this PR do?

WellKnown.load() resolved origins with a fail-fast Effect.forEach, so one unreachable origin failed the whole batch. The wellknown plugin called it through Effect.orDie, so that failure killed the plugin before it registered its transform — and every well-known integration disappeared, not just the dead one. Config.loadWellknown catches the same failure and returns [], so the remote config for the healthy origins went with it.

Each origin is now resolved independently. If one fails we keep its last known manifest, or skip it when nothing is cached. refresh() goes through the same path, so a temporary outage falls back to the cache and correctly reports "no change" instead of failing.

I also swapped the plugin's orDie for a logged catch. Worth noting it has to catch and continue — simply deleting orDie isn't enough, because yield* would still short-circuit before ctx.integration.transform(...) and the symptom would be unchanged.

The confusing part of the original bug is that auth login <url> prints "Authentication provider discovered" and then "Integration not found" for the same URL. Those come from different paths: wellknown.add only fetches the one origin you passed, so it genuinely succeeds, and the lookup afterwards reads a registry the dead plugin never populated.

It also only appears after a restart, since load() reuses the in-memory cache — which makes it look like whichever version you just installed broke it.

How did you verify your code works?

Two tests in packages/core/test/wellknown.test.ts, both of which fail on v2 and pass with this change (I checked by stashing the src/ changes and re-running):

• a closed port listed alongside a live fixture server — entries() returns only the live origin
• an origin that goes away after being loaded — refresh() returns false and keeps the manifest

From packages/core: bun run test test/wellknown.test.ts (5 pass) and bun run test test/config/config.test.ts (35 pass), plus bun typecheck.

I also reproduced the original failure end-to-end with the installed 0.0.0-beta-18684 client against packages/core/script/wellknown-server.ts: adding an unresolvable origin to wellknown:sources makes auth login fail for a healthy origin, and removing it fixes it.

Not in this PR, but related: WellKnown.remove() exists and nothing reaches it — no route and no CLI — so wellknown:sources only ever grows and the only way out of this state today is editing SQLite by hand. Happy to follow up if you want that exposed.
