Code Mirror "Silent" Crash Recovery

[codeCraft-Ritik]

Summary:

The editor currently uses a "Hard Error" state when it detects a sync failure between the Y.js document and the CodeMirror view. This forces a full browser refresh, which clears the session's chat history and UI state.

Description:

In PyIDE.jsx, the health check interval (line 133) monitors if yCollab has stopped syncing. If a mismatch is detected, setEditorCrashed(true) is triggered, replacing the entire editor UI with a refresh prompt. This is disruptive for collaborative sessions.

How to Fix:

Modify PyIDE.jsx State: Instead of a boolean editorCrashed, use a state that allows for a "re-syncing" status.

Implement handleSoftReset: Create a function that:

Temporarily nullifies the editorViewRef.current.

Re-runs the logic to initialize theyCollabextension with the existing ytextRef.current and awarenessRef.current.

Update UI: Replace the "Refresh Page" button with a "Repair Connection" button that calls the soft reset function.

While implementing this, ensure you wrap the re-initialization in a try-catch block. If the soft reset fails twice, only then should you fallback to the hard refresh screen to prevent infinite loops.
