Three categories of broken flags in registry/recipes.yaml:
1. --spreadsheet-id → --spreadsheet (10 occurrences)
The actual flag in sheets.rs is --spreadsheet, not --spreadsheet-id.
Every sheet recipe using this flag would fail.
2. --attendees → --attendee (repeated flag, 4 occurrences)
The calendar +insert helper uses --attendee with ArgAction::Append
for multiple attendees, not a comma-separated --attendees flag.
3. --duration → --end (4 occurrences)
The calendar +insert helper has no --duration flag. It requires
an explicit --end time in ISO 8601 format.
