test(sandbox): Isolate WSL detection in backend selection tests #947
Description
Problem
TestSelectBackendChoosesPlatformAdapterWithFallback mocks GOOS and executable lookup, but backend selection still reads the host's real WSL state. On WSL2, the missing-helper case returns BackendWSL instead of the intended non-WSL BackendUnavailable result.
Proposed change
Allow backend selection tests to inject WSL detection while preserving real detection as the production default. Add coverage for both non-WSL and WSL2 fallback behavior.
Acceptance criteria
go test ./internal/sandbox -run TestSelectBackendChoosesPlatformAdapterWithFallback/linux_helper_missing_falls_back_explicitly -count=1passes on WSL and non-WSL hosts.go test ./...passes.

Approved after rechecking current
main. Backend-selection tests still consult the real host WSL state, so the reported non-WSL expectation can change on WSL. The requested injection seam and WSL/non-WSL coverage are appropriately scoped. PR #948 is already active; please coordinate there rather than opening a duplicate.
