Thanks for the contribution! However, the fix isn't quite right here.

In htmx 2, htmx:afterSettle fired after the full swap-and-settle cycle completed. In htmx 4, the event model was redesigned with clearer before/after wrapping: the swap phase now has htmx:before:swap → htmx:before:settle → htmx:after:settle → htmx:after:swap. So htmx:after:swap in htmx 4 is the final event after everything (including settling) is done — making it the closest equivalent to the old htmx:afterSettle.

The upgrade-check tool's current mapping of htmx:afterSettle → htmx:after:swap is intentional and correct.
