Interactive review flow and stage orchestration

[SorraTheOrc]

Implement the interactive review flow for Stage 3:

• runReviewStage(session): Main stage function returning 'advance' | 'back'

  • Display palette summary table using outputTable()
  • Show coherence warnings (or skip message if <3 entries)
  • Present action menu: swap selection, add recipes, remove recipes, confirm and advance, go back
  • Swap: prompts user to pick a recipe, then re-enters explore audition for that recipe
  • Add: returns 'back' to go to Define stage (preserving current state)
  • Remove: prompts user to pick recipe to remove, removes from selections and manifest
  • Confirm: shows final confirmation prompt, then returns 'advance'
  • Back: returns 'back'

• Wire into src/tui/index.ts:

  • Import runReviewStage
  • Replace placeholder at lines 107-110 with proper dispatch (same pattern as explore stage)

Acceptance Criteria:

• runReviewStage displays the palette summary table on entry
• Coherence warnings are displayed for flagged entries
• Info message shown when <3 entries (coherence check skipped)
• All menu actions (swap, add, remove, confirm, back) work correctly
• Confirmation prompt is shown before advancing to Export
• index.ts properly dispatches to runReviewStage and handles advance/back
• Removing last entry warns user and prevents advancing with empty palette
