fix(gsd): address QA round 1

- Re-derive state from project root after stale/recoverable cleanup in
  guided flow; the assessment may have derived state from a worktree
  path that was cleaned up, leading to stale state being used downstream.
- Add test for the "none" classification path (clean startup with no
  lock and no paused session) to close coverage gap.
