Format and lint: fix revive violations in constants_test.go

[Copilot]

Ran make fmt and make lint, then fixed 5 revive violations in test code.

Changes

• pkg/workflow/sandbox.go: Aligned struct field comment spacing
• pkg/constants/constants_test.go:
  • Replaced explicit type declarations with type inference (4 instances)
  • Removed empty if block, replaced with blank identifier assignments

// Before
var job1 JobName = AgentJobName
if jobStr == stepStr {
    // This is fine - they can have the same string value
}

// After
job1 := AgentJobName
_ = jobStr  // Used for demonstration

All linters now pass with 0 issues.
