docs(ui-design): eliminate output-then-save ambiguity in workflow documentation

Clarified file writing patterns across UI design workflows to prevent confusion
between "generate content as output then save" vs "direct write to file" approaches.

Changes:
- extract.md: Merged Phase 2 & 3 to unify style synthesis and file write operations
  * Updated phase title to emphasize direct file writing
  * Added explicit note about internal processing without context output
  * Consolidated parse-and-write step into single atomic operation

- imitate-auto.md: Added clarifying comments for orchestrator file transformation
  * Documented that Phase 2 uses orchestrator-level read-process-write pattern
  * Explained this as performance optimization to bypass consolidate phase

The entire UI design workflow now consistently follows clear file operation patterns
with no ambiguous intermediate output steps.
