fix: adapt SourceDateEpoch to upstream refactored dep check

Upstream/main restructured the dependency error handling in install.go
and upgrade.go from a nested-if block (if DependencyUpdate) to an
early-return pattern (if !DependencyUpdate). Adapt the feature's
Manager construction to match the new code structure.
