Prevent recipe wrangle from writing partial batches

[mborodii-prog]

Summary

• Prevent nested recipe writes from running when
  ecipe is used as a wrangle.
• Fix batch scenarios where an attached recipe with its own write step overwrote spreadsheet output once per batch, leaving only the final partial batch.
• Add regression coverage for 1000 input rows with �atch_size: 100, ensuring only the outer final write persists all 1000 rows.

• Targeted batch tests passed: 6 passed.
• python -m py_compile wrangles/recipe_wrangles/main.py tests/connectors/test_recipe.py passed.
