### What changes were proposed in this PR?
This PR refactors the package structure by moving all Amber engine code from

namespaced under the Apache Texera organization.
**Key Changes:**
1. **Directory Structure Migration** - Moved all source directories:
- Scala/Java sources: 8 modules moved
- Protobuf definitions: 14 files moved
- Python proto generated code: moved under new namespace
- Frontend TypeScript proto: moved under new namespace
2. **Code Updates** - Updated across 707 files:
- Package declarations in 576 Scala/Java files
- Import statements across all Scala/Java files
- 57 Python files updated for new proto imports
- 14 Protobuf files updated with new Java package
- 2 TypeScript files updated with new import paths
- Configuration files (cluster.conf)
- String literals containing class names for reflection/dynamic loading
