Discover sibling projects that share the same `trace_id` (Phase 1 banner).
Changed onReturns an empty siblings list when the trace is single-project — never 404. Project names are included so the UI can render navigation links without a second round-trip. See ADR-027 §3 for the full auth model and topology-disclosure trade-offs.
