When the user explicitly says "переходим на фазу <X>" (or "next phase"), generate and write the artifacts for that phase directly to files without previewing content in chat.
Behavior:
- •Treat this as an explicit transition signal.
- •Write artifacts immediately to their target files.
- •After writing, report the file paths and a brief summary of what was written.
- •Accept edits on request; do not re-preview unless asked.
