Add Pester 6 unit tests for `Initialize-PSBuild`. **Scenarios to cover:** - Environment variables and build properties are set correctly - Path resolution works on both PS 5.1 and PS 7 (see #53) - Mock `Set-BuildEnvironment` to avoid filesystem side effects No fixture module needed. Target Pester 6.0.0 with classic `Should` syntax — see notes on #17. Parent issue: #17
