Fix summary field naming for consistency (v0.5.2)

Reverted field naming from ShortSummary/Summary back to ShortText/Text in SummaryMetadata.

Rationale: "Summary" is redundant when fields are already in SummaryMetadata struct.
This provides cleaner naming: SummaryMetadata.Text vs SummaryMetadata.Summary

Changes:
- internal/bridge/events.go: ShortText + Text (JSON: short_text, text)
- pkg/conversation/state.go: ShortText + Text (JSON: short_text, text)
- pkg/orchestrator/orchestrator.go: Updated summaryMetadata initialization
- cmd/run.go: Updated state metadata population
- All test files updated accordingly

All tests pass, no breaking changes to external APIs.
