DEFAULT_VAULTS was hard-coded to the main repo path, causing the Vault API to read stale/duplicate files when running from worktrees. Now uses Vite's define to inject the correct path at build time. Also fix theme heading titles (remove redundant "Theme" suffix) and make smoke tests resilient to Theme-type notes appearing first in the note list.
