Add affinity-path spans for owner checks, HTTP/RPC forwarding, local dispatch, and forwarded execution; propagate W3C trace context across session-affinity hops; add Redis/HTTPX/SQLAlchemy auto-instrumentation; dispatch forwarded affinity work concurrently with bounded global concurrency while preserving per-session FIFO ordering. Tracked by PR #6164.
