Why: Independent review found scratch runs still called the project
context resolver, and chat intent routing plus system.intent re-dispatch
could deliver rdm.* commands with a scratch host project.
Evidence: go test ./internal/runmgr ./internal/cmdbus ./internal/app
./internal/server ./internal/store pass locally (SELF); CI is authoritative.
Impact: ProjectContext returns nothing when project context is disabled;
Bus.Dispatch applies a host-project guard to every request carrying a host
project, rejecting rdm.* and formal project commands on scratch hosts;
scratch lookups that fail keep isolation gates closed.
