Greptile Overview

Greptile Summary

This PR fixes parameter passing issues to queueEvents and processEvent that have existed since the Remix migration (v0.8). The functions' signatures were updated to require 5 and 3 parameters respectively, but several call sites were still using the old signatures.

Changes made:

• state.js: Added missing prepend parameter (value: false) to queueEvents call in queueEventIfSocketExists function
• state.js: Replaced direct queueEvents calls with queueEventIfSocketExists for _clear_session_storage and _remove_session_storage events to ensure proper null checking
• format.py: Updated format_queue_events to generate JavaScript code that passes all required parameters (prepend, navigate, params) when calling queueEvents and processEvent

The fix ensures that callback functions generated by rx.call_script now correctly queue events with all required parameters.

Confidence Score: 5/5

• This PR is safe to merge - it fixes critical bugs in parameter passing that could cause runtime errors
• The changes are straightforward bug fixes that correct parameter mismatches between function signatures and call sites. All modifications follow existing patterns in the codebase, and the fix addresses issues that have existed since v0.8. No logic changes were made beyond adding the missing parameters.
• No files require special attention
