Title:

test(utils): Add unit tests for all utility modules in pkg/utils folder

Description:

Currently, the following utility files in the utils/ folder lack full test coverage:

This issue tracks the gradual addition of table-driven unit tests for each of these files. All tests will follow Go testing best practices and be covered under separate PRs.

Goal:

Achieve 90–100% test coverage across the utils/ folder.

Progress Tracker:

• stringutils.go
• retry.go
• exec.go

Note: Exec function is yet not covered because it it external-system heavy and I would like feedback before mocking

Additional Notes:

Tests will be added incrementally via well-scoped PRs and linked to this issue. This allows for easier review and faster feedback.
