Refactor: Remove CDC pipeline buffering for streaming
Remove ProcessCDCEntries and related merge/grouping infrastructure
that was blocking streaming. CDC entries are now converted directly
to statements inline without intermediate buffering.
- Remove GroupByIntentKey, MergeGroup, ValidateCDCEntry
- Remove CDCPipelineConfig, CDCPipelineResult types
- Keep only ConvertToStatement for O(1) per-entry conversion
- Update handler.go to convert entries inline
- Delete 1300+ lines of pipeline code and tests
