chore(release): v1.11.1 — source-aware vitals + Coach long-term memory

Closes the three v1.11.0 follow-ups: cross-source vital de-duplication
(measurement rollups resolve overlapping sources to the priority-ladder
canonical reading across charts, summaries, insights, and the live
fallback), the Coach's rolling encrypted conversation summary, and
durable encrypted personal facts with a list/forget surface.
