Extract into helper functions

Break down complex or deeply nested code into smaller, well-named helper functions to improve readability and maintainability. Extract code into helpers when:

1. A function contains deeply nested logic
2. Similar logic is repeated
3. A function handles multiple concerns
4. A block of code is complex enough to benefit from its own descriptive name

Example of improving complex nested code:

Before:

function processNextEditData(filePath, beforeContent, afterContent, cursorPosBeforeEdit, ...) {
  // Get the current context data
  const currentData = (global._editAggregator as any).latestContextData || {
    configHandler: data.configHandler,
    getDefsFromLspFunction: data.getDefsFromLspFunction,
    recentlyEditedRanges: [],
    recentlyVisitedRanges: [],
  };

  void processNextEditData(
    beforeAfterdiff.filePath,
    beforeAfterdiff.beforeContent,
    beforeAfterdiff.afterContent,
    cursorPosBeforeEdit,
    cursorPosAfterPrevEdit,
    this.ide,
    currentData.configHandler,
    currentData.getDefsFromLspFunction,
    currentData.recentlyEditedRanges,
    currentData.recentlyVisitedRanges,
    currentData.workspaceDir,
  );
}

After: ```typescript interface ProcessNextEditDataParams { filePath: string; beforeContent: string; afterContent: string; cursorPosBeforeEdit: Position; cursorPosAfterPrevEdit: Position; ide: IDE; configHandler: ConfigHandler; getDefsFromLspFunction: GetLspDefinitionsFunction; recentlyEditedRanges: RecentlyEditedRange[]; recentlyVisitedRanges: AutocompleteCodeSnippet[]; workspaceDir: string; }

function getCurrentContextData(): ContextData { return (global._editAggregator as any).latestContextData || { configHandler: data.configHandler, getDefsFromLspFunction: data.getDefsFromLspFunction, recentlyEditedRanges: [], recentlyVisitedRanges: [], }; }

function processNextEditData(params: ProcessNextEditDataParams) { const currentData = getCurrentContextData(); // Process using structured parameters… }
