IRC plugins now format datetimes as "Wed Mar 11, 10:00 PM EDT" instead
of raw ISO 8601. Configurable timezone defaults to America/New_York.
Adds !lastshow N command to both Limnoria and Sopel plugins, returning
track N from the previous week's show via existing API endpoints.
Made-with: Cursor
- Fix format_playlist truncation: +4 → +5 to account for ", ..." suffix
- Add API error logging to all Sopel command handlers (matching Limnoria)
- Add long-track truncation test case
