refactor: reorganize package structure for better domain grouping

- telemetry/ → observability/ (with log/ merged as observability/logger/)
- jsondiff/, rql/ → data/jsondiff/, data/rql/
- Fix otelhhtpclient typo → otelhttpclient
- Inline utils/error_status into observability/otelgrpc/status.go, delete utils/
- Rename log package to logger to match directory
- Update all internal imports and README
