[deep-report] Close the MCP telemetry observability gap - rpc-messages.jsonl/gateway.jsonl missing on most sampled runs #48674

Description

The Observability Coverage Report (2026-07-28, #48462) sampled 8 recent runs and found only 1 had complete firewall + MCP telemetry coverage. 5 firewall-enabled runs were missing access.log entirely, and 5 MCP-enabled runs were missing both gateway.jsonl and rpc-messages.jsonl (including PR Sous Chef twice and Daily Reliability Review). A prior fix (#48090, closed) added per-run firewall access.log artifact upload, but does not appear to cover MCP telemetry, and firewall coverage still is not universal post-fix. Separately, the Daily Security Observability Report (#48042, 07-25) reported it could not get any firewall data at all because the agenticworkflows logs --firewall tool timed out - this DeepReport run independently reproduced that same context deadline exceeded timeout on 3 separate attempts with different parameters today, confirming it is a live, reproducible platform bug (already tracked in #47928, #48136, #48299, #48539 - please prioritize a fix, as it now blocks both DeepReport's and Security Observability's workflow-log intelligence gathering).

Expected Impact

Extend the artifact-upload pattern from #48090 to MCP telemetry files (gateway.jsonl, rpc-messages.jsonl) so both firewall and MCP observability are consistently captured per run, restoring the ability to debug security/telemetry issues after the fact.

Suggested Agent

Observability workflow maintainer / Code Quality agent.

Estimated Effort

Medium (1-4 hours)
