Turn event log lines into records

A repository service writes one event per log line: 2025-03-03T00:02:37Z PushEvent ml-koi418 tidewater/smartqueue. Turn the well-formed lines into records and count the ones that aren't.

Functionparse_events(lines)

Shapea UTC time YYYY-MM-DDTHH:MM:SSZ, an event type made of letters ending in Event, an actor login (letters, digits, - or _), and a repository owner/name, separated by single spaces

Returns(records, skipped): a list of {"time", "type", "actor", "repo"} dictionaries in order, and how many lines didn't have the shape
