refactor: remove unused code and fix documentation

- Remove CorrelationKeyFull() alias, use CorrelationKey() everywhere
- Remove duplicate TimeProvider interface from ports/source.go
- Remove unused time import from ports/source.go
- Update README.md: replace ./build.sh and ./test.sh with make commands
- Update RPM package names in README to match current version (1.0.3)
