Indiana 2f4832a3a8 Wire Workstream K's summon-pipeline integration into G's ingestion handoff
Both G and K were built independently against the paper contract and
correctly left this connection point for the integrator (documented in
both their reports). Calls process_device_reading_for_summon from
_process_reading, skipping array-valued readings (no defined single
scalar baseline for those). Adds an end-to-end integration test that
connects a real /ws/session, posts device telemetry through it, and
confirms an anomalous reading actually reaches the live session as an
anomaly_ack — proving the two independently-built pieces genuinely
connect, not just that each compiles.

165/165 backend tests pass.
