Test ed5e6d6820 fix: auto-provision theme files on vault open for any vault
seed_vault_themes now writes individual missing/empty files instead of
skipping when the theme/ directory already exists. A new
ensure_vault_themes Tauri command is called by useThemeManager on every
vault open so vaults without a theme/ folder get default.md and dark.md
seeded automatically.
