Fix all module imports to use src. prefix

- Updated all imports from 'from langlab' to 'from src.langlab'
- Updated all imports from 'import langlab' to 'import src.langlab'
- Fixed imports in source files, test files, and notebook
- Updated documentation examples to use correct import format
- Added emergent/ directory to .gitignore to avoid nested repo issues
- Fixed mypy type errors in test files by adding None checks for seed parameters
- Updated patch decorators to use src. prefix
- Applied black formatting to test files

This ensures consistent import structure across the codebase.
