Merge master and reconcile Dot with the released MCP gateway

Reuse scoped browser and device consent, verified client metadata, signed event admissions and warm-standby gates. Preserve the dedicated agent resource and Runner authority. Regenerate the Dot-only migration after the merged gateway history and cover issuer, company, viewer and token isolation.
