In `@libs/differ/src/index.ts`:
- Around line 4-7: The ENABLE_DIFFER_V4 gate in index.ts only treats exact
'false' and '0' as opt-out, so legacy values like FALSE, False, or an empty env
var now incorrectly enable DifferV4. Update the logic around ENABLE_DIFFER_V4 to
normalize the environment value before checking it, and preserve the old
behavior for blank or case-variant opt-out values while still defaulting new
installs to DifferV4. Keep the fix localized to the feature-gate constant so the
DifferV3/DifferV4 selection remains backward compatible.
