The proxy now relays the upstream HTTP status. On 403/412-style answers the stripped body is the site's own anti-bot challenge page, which until now rendered as if it were site content (bilibili 412 风控 report). classifySiteStatus/sitFailureCopy in src/model/proxy-errors.ts classify the relayed status — 403/412 → site-blocked, 429 → rate limited, other 4xx/5xx → site-error — and browser.ts renders honest human copy with a suggestion to open the address externally. Timeout/abort behavior from #25/#26 is unchanged.
…39) Mocks the proxy contract exactly as the Worker ships it - HTTP 200 envelope carrying the target site's {status: 412} - so reordering the render if/else chain in browser.ts back to the success-first shape renders the anti-bot challenge body and fails CI. Asserts blocked title/copy/status band and that no challenge marker survives in any rendered text.

PR body
Closes #39 (proxy half already merged: vectojs/webos-proxy#1).
Honest blocked-page handling for the WebOS browser:
src/model/proxy-errors.ts: the proxy's relayed upstream status (not the Worker's 200) classifies the outcome — 403/412 → "site blocked the request" copy with an open-externally hint, 429 → rate-limited wait-and-retry, other 4xx/5xx → site-error. Anti-bot challenge pages can no longer render as content.Live verification (production proxy): wikipedia/github/HN 200 real content; bilibili 412 → honest blocked copy (CF egress IP class is hard-blocked by bilibili risk control regardless of headers).
