Normalize assignment spacing while keeping values, quotes, export prefixes and comments. Duplicate keys stay in their original relative order.
Supported .env syntax
Keys are case-sensitive and use letters, digits and underscores; the first character must be a letter or underscore. Optional export prefixes, empty values, single/double quotes and quoted multiline values are supported. Outside quotes, # begins a comment.
Backslash-escaped quotes are kept inside quoted values. Escape sequences, variable references and commands are kept as text; nothing is expanded or executed. Backtick quoting and shell scripts are not supported. Parser conventions vary by framework.
Cleanup uses LF line endings, preserves quoted value content and keeps duplicate assignments. Example generation removes duplicates and comments as well as values. Key comparison ignores order and duplicates.
