## This PR
- updates the code default ADR to use `FLAG_NOT_FOUND` errors codes
instead of an undefined value.
### Notes
This update will have nearly identical end results but will be easier to
implement and more consistent. Core to this change is switching from
using an empty value as the indicator to using the `FLAG_NOT_FOUND`
error code. While this may seem odd at first, it's in line with the
behavior a user sees when first releasing a disabled flag. This will
allow users to `create a new disabled flag` -> `enable the flag for a
subset of users without impacting others` -> `enable the flag for
everyone` -> `deprecate the flag`.

## This PR
- ADR to add support for explicitly deferring to the code default.
### Notes
This has been a challenge for users because enabling a feature for
targeting requires a default variant to be used, which may not match the
default used in code.
