This question runs in a pre-configured Salesforce environment - no personal connection required.

Write a method that finds every Opportunity in the 'Prospecting' stage, sets its NextStep field to 'Schedule discovery call', updates the records in the database, and returns the number of Opportunities that were updated. The operation must be idempotent: running it repeatedly sets the same value and returns the same count.

Examples:

Call: annotateProspectingOpportunities() Returns: 4 Explanation: All 4 Prospecting Opportunities get NextStep = 'Schedule discovery call' After running: Every Opportunity with StageName = 'Prospecting' has NextStep = 'Schedule discovery call' No Opportunity in any other stage is modified

Note: The exact count depends on the org's data. Query the Prospecting Opportunities rather than assuming a fixed number.
