refactor: resolve merge conflicts — combine main improvements with token normalization

- .gitignore: keep both graphify-out/ entries and main's .gitnexus entry
- ScriptCodeBlock/ScriptPreviewModal: take main's border-border and text-accent-text
  for filename labels; use neutral ghost style for Save button in ScriptCodeBlock;
  use bg-accent (normalized from bg-primary) for Save button in ScriptPreviewModal
