fix(tui): show commentary-phase text when no final_answer blocks present

CCcassiusdjs · claude · CCcassiusdjs · commit e40fef2b5de2 · 2026-04-20T10:10:14.000-03:00
TUI was invisible for messages with only commentary-phase text blocks because extractAssistantVisibleText returned undefined when hasExplicitPhasedTextBlocks=true and no final_answer phase existed. Add commentary-phase fallback before unphased extraction so streaming deltas and final messages are visible during the commentary phase and when models omit the final-answer tag entirely.
