Fix protobuf runtime panic on startup

Regenerated protobuf stubs and bumped google.golang.org/protobuf from
v1.36.10 to v1.36.11 to match protoc-gen-go v1.36.11. The version
mismatch caused a panic in filedesc.unmarshalSeed during init().

+## MCP Deployment
+
+MCIAS is **not** managed by MCP and does not run on rift. Because MCIAS is the
+authentication root for the entire platform — including MCP itself — running it
+under MCP would create a circular dependency. Instead, MCIAS runs as a systemd
+service on a separate VPS (`svc.metacircular.net`).
+
+All deployment, upgrades, and operational tasks use systemd directly on the VPS.
+See the [Installation](#installation), [Routine Operations](#routine-operations),
+and [Upgrading](#upgrading) sections above for the relevant procedures.
