Fix stdio sheets bug: remove output_spreadsheet_title from StdioResultsInput

output_spreadsheet_title requires Google OAuth tokens which are only
available in HTTP mode. Exposing it in stdio mode caused the function to
attempt a Google API call, fail, and return early without writing the CSV
— silently breaking the tool's primary functionality.

Also bump duplicate-sheet guard from max_results=5 to 50 and document
the inherent TOCTOU race condition.
