feat(#268): display enrichment progress in full_techniques mode

- Add enrichment SSE event types to SSEEventType union
- Add enrichment state tracking (phase, message, status per step)
- Handle enrichment_start/complete/error events in reducer
- Add 'enrichment' stage to currentStage
- Add enrichment status indicator to ProgressTopBar
- Update FullTechniquesProgress to show enrichment stage messaging

Closes #268
