Add stdlib mock for io.Closer and update mockgen install instruction
Merged May 2026
Updated the Makefile to include generation of the missing mocks/io/mock_closer.go, ensuring all stdlib mocks used by the test suite can be regenerated through a single make mocks command
Regenerated all project mocks using mockgen v1.6.0, resolving the stale generated files reported in Issue #564 and synchronizing generated code with the latest interfaces
Addressed maintainer review feedback by reverting unrelated go.mod and Makefile changes, keeping the PR focused solely on mock generation
Resolved cross-platform generation issues by matching the project's Go and mockgen versions, producing output consistent with the repository's expected tooling
Updated 40 generated mock files, removing outdated code and ensuring future mock regeneration remains reproducible and maintainable
Closed Issue #564 by restoring a complete, reproducible mock generation workflow without introducing functional or API changes
