chore: complete code quality audit fixesv1.2.6

- Fixed failing test in config_test.go (hardcoded date)
- Addressed unchecked error returns from Close() operations
- Refactored large functions to follow SRP (run.go and main.go)
- Added documentation to exported identifiers
- Fixed linting errors (error message capitalization, errcheck)
- Bumped version to v1.2.6
