mirai 2.7.4

Updates

• The collect_mirai() .progress option now accepts a named integer (the name being a cli progress bar id) to update an existing progress bar once per collected result, rather than creating a new bar (#663).
• The .progress collection option now ignores elements of a named list that do not match cli::cli_progress_bar() arguments (such as caller, injected by purrr's .progress specification) instead of erroring (#667).
• Fixes the .progress collection option leaking an envir binding into the global environment, and closing an existing cli progress bar in the calling frame when creating its own bar.
• Fixes promises never resolving if an mirai completes during the short window of the as.promise() call itself (thanks @dawiegriesel, #656).
• Requires nanonext >= 1.10.4.
