unkinben c39703ed0d fix: getenv treats an explicitly-empty value as unset (#85) ...

Fixes #69

## Why
`getenv` returned the fallback whenever `os.Getenv` was empty, so an intentionally-empty env var could not override a non-empty default.

## Changes
- Use `os.LookupEnv` to distinguish unset from set-but-empty.

## Validation
- `make e2e` passes.
