Convert .env files back into nested YAML.

What is .env → YAML?
The inverse of YAML→.env: it parses KEY=VALUE lines and reconstructs nested YAML structure from '__'-separated keys.
How it works
Each line is split on the first '=', comment lines skipped, and the key path is walked to build nested objects; numeric segments create arrays.

Examples
Environment to config
Convert a .env file into a nested YAML config — dotted keys become nested maps for a cleaner project structure.
Common mistakes
Expansion vs literal values
$VAR-style references may be literal or expanded. The converter preserves them verbatim unless you opt into expansion.
Frequently asked questions
How are quoted .env values handled?
Quotes are stripped according to .env rules, and the resulting YAML types are inferred.
Can I group keys into sections?
Yes — dotted prefixes like DB_HOST group under a db: section automatically.
