Greptile Summary

Changed REFLEX_CORS_ALLOWED_ORIGINS environment variable parsing to use comma as delimiter instead of colon, fixing the issue where URLs with colons (like http://localhost:3000) were incorrectly split.

• Introduced SequenceOptions dataclass to configure sequence parsing with custom delimiter and strip options
• Modified cors_allowed_origins field to use Annotated[Sequence[str], SequenceOptions(delimiter=",")]
• Updated interpret_env_var_value to extract and apply SequenceOptions from Annotated type hints
• Added comprehensive tests for both the general annotated sequence functionality and CORS-specific behavior
• String sequences benefit from automatic whitespace stripping via recursive interpretation, regardless of strip setting

Confidence Score: 5/5

• This PR is safe to merge with minimal risk
• The implementation is clean, well-tested, and solves the stated problem without breaking existing functionality. The design uses type annotations elegantly to extend the env var system. Tests cover the main use case and edge cases.
• No files require special attention
