[Feature Request] Create a Zed extension with VS Code extension feature parity

[sanathusk]

Description

Request to create a Zed editor extension that provides feature parity with the existing VS Code extension (@env-spec).

Motivation

Zed is an increasingly popular code editor, and many developers use it for working with .env files and environment variables. Having a native Zed extension would provide a better experience for Zed users.

Features to Implement

The Zed extension should include all features from the VS Code extension:

1. Syntax Highlighting - Proper syntax highlighting for .env files and .env.schema files
2. Comment Continuation - Smart comment continuation behavior
3. Toggle Comment - Ability to toggle comments on/off
4. Hover Info - Show hover information for variables
5. IntelliSense/Autocomplete:
   • Decorators autocomplete
   • Type suggestions
   • Variable resolvers
   • Enum value suggestions
6. Inline Diagnostics - Show inline diagnostic errors for schema validation
7. Variable Resolution - Support for variable interpolation and references

Additional Information

The VS Code extension serves as the reference implementation. A Zed extension would follow the same patterns and provide the same level of functionality for Zed users.

Thanks for this! We'll have a look at this as soon the IntelliJ version is complete (almost there!)
