Diego Rodrigues de Sa e Souza 20ea78c943 feat(sse): restate agentrouter quota 403/400 as retryable 429 with provider-scoped error rules (#10335)
agentrouter.org signals temporary quota exhaustion with HTTP 403/400 and a Chinese body (用户额度不足) instead of 429, so clients like Claude Code treat it as permanent and abort, and the fallback engine classified it as a generic apikey AUTH_ERROR.

New registry open-sse/config/upstreamStatusRestatement.ts restates those statuses to 429 with a synthetic Retry-After at a single hook in chatCore's providerFailure block (after parseUpstreamError), so classification, combo aggregation and the client response all see a retryable error. 无权访问模型 (permanently no model access) is veto-listed and never restated.

agentrouter classification rules are registered in providerErrorRules.ts and reach the real checkFallbackError path through resolveRuleMatchBody() with an exclusive FULL_TEXT_RULE_PROVIDERS allowlist — every other provider keeps its previous behavior byte-for-byte.

Known limitations tracked in #10334: the rules' scope field is informational (persistence applies per-model lockout for agentrouter), the 403-only model-access rule has no production path yet, and errors embedded in 200 SSE streams are not restated.
