* fix(cliproxy): guard against empty upstream SSE responses in agy profile When CLIProxyAPIPlus drops unsigned thinking blocks during sub-agent execution, the response stream can contain no content_block_start or message_delta events. This causes Claude Code CLI to crash with "No assistant message found". Add empty response detection in the tool sanitization proxy's streaming handler. Both the pipe-through and SSE-processing paths now track whether meaningful content was received. If upstream sent data but no content blocks on a 200 OK, a synthetic minimal valid SSE response is injected to prevent the client crash and surface a clear error message. Closes #350 * fix(cliproxy): improve empty response detection and add tests Address code review findings: - Remove message_delta from content detection (lifecycle event, not content); only content_block_start indicates actual content - Add try-catch in end handlers to handle client disconnects gracefully - Add 3 integration tests: empty stream injection, normal stream passthrough, 4xx/5xx non-injection * fix(cliproxy): avoid duplicate message_start in synthetic response Track whether upstream already sent a message_start event. When injecting the synthetic error response, omit message_start if upstream already sent one, preventing duplicate events in the SSE stream. Addresses PR review feedback from ccs-reviewer[bot]. * test(cliproxy): add SSE processing path and real failure mode tests Address code review observations: - Add test exercising SSE processing path (sanitized tool names) for empty response detection, ensuring both code paths are covered - Add test mirroring real failure mode where upstream sends only message_start then ends abruptly (no message_delta/message_stop) - Document duplicate message_start assumption with inline comment
