* test(integration): isolate every multi-worker integration suite by default
Per-worker database, Redis, upstream and proxy were opt-in for management,
accounting, providers and extensions. mcp, security and cost ran 4 to 8
xdist workers against one shared proxy, database and Redis, and those suites
hold most of the integration flakes CircleCI records. Every run with more than
one worker now builds a private stack per worker, run_integration.sh no longer
starts or exports the shared proxy, upstream, database or Redis in that mode,
and each worker's scripted upstream runs in its own process instead of a
thread in the pytest controller.
Worker gateways get what the shared proxy used to provide: a peer for
management and mcp, the scripted cost map for cost, stdio MCP servers, and
coverage for mcp. mcp coverage now measures lines through sys.monitoring,
because branch measurement on CPython 3.12 uses the trace function and that
made a covered proxy take about 4x as long to become ready, which is why the
shared mcp proxy kept missing its 90 s readiness wait. Routing parity
snapshots now also read the worker databases, since its cost and mcp runs use
several workers. The security per-worker fixture is redundant and removed
* test(integration): give the nested probe root the files a worker gateway needs
Two worker probes now run isolated, so the nested controller boots a real per-worker upstream and proxy from the probe root. That upstream imports the fake OpenAI server and the cost map modules, and the proxy reads proxy_config.yaml, none of which the probe copied. The nested run also drops INTEGRATION_COVERAGE_FILE so it never writes into an outer coverage file
* test(integration): budget nested multi-worker runs for their worker stack boots
A nested run.py database run with more than one worker now boots a private database, Redis, upstream and proxy per worker, one after another, before any case runs. The fixed 60 s subprocess timeout left no room for that, so the 2 worker probes sat at 57-60 s on CircleCI. The subprocess budget is now the old 60 s plus 30 s per worker stack, and the outer pytest timeout keeps its previous 30 s of slack on top. 30 s is the slowest worker proxy readiness recorded in startup.json on the integration-cost job of workflow e09b108b (21.6-30.3 s on 4 CPUs, 2026-10-12)

Key the schema shard's full clone on artifact-name, since main removed the
unit-flag input. Give each owned Redis its own log file again. Hand the
realtime transcription tests main added a logging object whose dispatch
handlers are awaitable, so the per-test logging drain no longer waits on a
MagicMock task forever
