Configuration desync silent failure - spark config set changes are ignored by advisory doctor

Best target repo

{"vibeship-spawner-ui" => "Mission Control, Kanban, Canvas"}

Page, command, module, or repo

spark config set / spark advisory doctor

What got confusing?

Memory or domain chips

What did you expect to happen?

Changes made with spark config set should be reflected immediately when running spark advisory doctor

What actually happened?

spark config set confirms the change was saved but spark advisory doctor continues using the old configuration value

Safe details

Reproduction:

1. Run: spark config set advisory.preferred_provider [any value]
2. Run: spark advisory doctor
3. Doctor shows old value, not the new one
   This is a silent failure - users think they configured the system but the AI ignores them

Suggested improvement or PR link

Ensure config set writes to the same source that advisory doctor reads from. Add a confirmation step that shows the active value after saving
