fix: scout stale-state overwrite + correct micro model ID

- Scout was loading state at start, then calling addWorkItem (which saves
  atomically), then overwriting with stale state at end — wiping the queue.
  Fixed: reload fresh state before final save to preserve work items.
- Changed micro tier from gemini-2.5-flash-lite-preview (invalid) to
  gemini-2.5-flash-lite (correct OpenRouter model ID).
