[Tech Debt]: Simplify unset of VIRTWORK_ env vars

[mrhillsman]

Category

Code quality / code smell

Description

Reported by: @OchiengEd
Original issue: #25

The if statement to find env vars prefixed with VIRTWORK_ and to unset them is unnecessarily complex, confusing, and potential maintenance problem in the config test setup.

Severity

Medium — increases maintenance burden or risk of future bugs

Affected Files

• internal/config/config_test.go - L42-L49

Proposed Fix

Edmund proposes using strings.HasPrefix and strings.Cut to find env vars prefixed with VIRTWORK_ env vars and the entire env var key to unset

Area

Testing

Architecture Layer

Layer 1 - Infrastructure (config, cluster, cloudinit, audit)
