v3.1.1

Bug Fixes

• EnvVar Descriptor Protocol: EnvVar now works in plain classes without @proto decorator
  • Previously EnvVar @ "VAR" | default returned _EnvVar object in plain classes
  • Now auto-resolves via __get__ descriptor when accessed as class attribute
  • Fixes: AttributeError: '_EnvVar' object has no attribute 'decode'

API Changes

• Removed .get() method: Use class attribute access instead
  • Old: EnvVar("PORT", dtype=int).get()
  • New: class C: port = EnvVar("PORT", dtype=int) then C.port
  • Use invalidate_cache() to force re-read from environment
