Summary

This PR introduces significant improvements to HelixDB across documentation, compiler robustness, and tooling. The changes span three main areas:

Documentation Updates: The README has been streamlined with a clearer tagline ("open-source graph-vector database built in Rust"), corrected HQL code examples, and simplified messaging to make the project more accessible to newcomers.

HQL Compiler Robustness: The most substantial changes involve replacing panic-inducing assert! statements and unreachable! calls throughout the semantic analyzer with graceful error handling. Key improvements include:

• New E210 error code for type validation when identifiers should be ID types
• Enhanced type checking with check_identifier_is_fieldtype utility function
• Fixed location tracking in the parser to ensure accurate error reporting
• Converted function return types to Option<T> for better error propagation

Tooling Improvements: CLI experience has been enhanced by removing debug print statements and fixing diagnostic formatting so users see properly rendered error messages with source context. Docker builds have been optimized with more targeted dependency caching.

PR Description Notes:

• The PR description is mostly empty template content and doesn't describe the actual changes made
• Related issues section shows "Closes #" without specifying an issue number
• Checklist items are unchecked despite the PR being ready for review

Please double check your latest force push, it removes some env file stuff. You probably meant to merge unless you wanted to remove that from this release
