Function ApplyDeltaChanges 

fn ApplyDeltaChanges(
    Lines: &[String],
    EOL: &str,
    RPCChange: &[RPCModelContentChangeDTO],
) -> Vec<String>

Applies delta changes to the document text and returns the updated lines.

This function:

1. Sorts changes in reverse order (by start position) to prevent offset corruption
2. Converts line/column positions to byte offsets in the full text
3. Applies each change (delete range + insert new text)
4. Splits the result back into lines

Arguments

• Lines - The current document lines
• EOL - The end-of-line sequence to use
• RPCChange - Array of changes to apply

Returns

Updated lines vector after applying all changes
