Port of upstream grok-build 1.0.0/1.0.1-window retry policy. - is_retryable_api_status: 429 plus any 5xx except Cloudflare 525/526 (origin TLS handshake / invalid certificate — never clears on its own), replacing the 500|502|503|504|520 allowlist so the 521-524, 529, and 530 edge pages an outage serves actually retry. - The generic retry path clamps a server Retry-After to MAX_RETRY_BACKOFF (30s) and jitters it: Cloudflare 52x pages ask for 60-120s, which across the budget stalled a turn ~28 minutes. The 429 path keeps the full (parse-capped) Retry-After under its low attempt cap, and jitter is shared via jittered().
