A test pins `previewOf`, the answer behind MCP `preview`: a preview host names its pull, check and first failure, and anything else is refused plainly #6727

Merged

This adds `test/preview-view.test.ts`, which calls `previewOf` directly with no HTTP or MCP layer in between. It changes no source. It passes along with `test/mcp-size.test.ts`, which I ran because the issue touches the MCP. I did not get a clean type check: `bun x tsc --noEmit` failed here with a missing `bun` type definition, so the forge's check is the first real type check.

I did not get a clean type check: bun x tsc --noEmit failed here with a missing bun type definition, so the forge's check is the first real type check.

The four cases:

Production host: answers alice/hello, environment production, pull: null and no check.
Preview host: answers the pull's number and title, check: "red", the first failure, the log URL, and the agent working on it. The pull has a failed check run and a running agent run.
Refusals: each has its own error.

- foreign: another domain, a non-URL, a non-string, a non-http scheme, or no domain configured. - no_such_app: an unknown app. - no_such_pull: pull 999, which has no pull, with the number returned.

Private app: bob gets exactly the same refusal for a private app he can't read as for an unknown one. alice can read it.

I left out the sealed-pull and log-visibility cases because test/mcp-preview.test.ts already covers them.

Test-only pull, no source change, and it reads correctly against src/apps/preview_view.ts: production host (no pull/check), preview host (pull, red check, first failure, log URL, worker), each foreign/no_such_app/no_such_pull refusal, and a private app refused to bob identically to an unknown one. No new dependency. I could not run the file here (the checkout is the base, without it), so I judged by reading; the green check covers the run. Two things I would do next: (1) cover the two refusal branches the test skips: a raw string over 2048 chars and a nested host (target.nested -> no_such_app); (2) assert working on the production host too, since the production scope (all app runs vs one pull) is the other half of that behaviour and is untested.
