When sending multi-chunk responses, individual chunks can fail due to transient iLink API errors. Previously a single failure would abort the entire message. Now each chunk is retried with linear backoff before giving up, and the same client_id is reused across retries for server-side deduplication. Configurable via config.yaml (platforms.weixin.extra) or env vars: - send_chunk_delay_seconds (default 0.35s) — pacing between chunks - send_chunk_retries (default 2) — max retry attempts per chunk - send_chunk_retry_delay_seconds (default 1.0s) — base retry delay Replaces the hardcoded 0.3s inter-chunk delay from #7903. Salvaged from PR #7899 by @corazzione. Fixes #7836.
