notefeed 0.28.0: scheduled notes and changeable dates

notefeed 0.28.0 is out.

• A note posted with a date in the future is scheduled. Readers see it on the read page, in RSS and in the read API only from that time on. You see it marked as scheduled.
• You can change a note's date at any time: in the edit form on the note's page, with PATCH and date, with notefeed update --date in both clients, or by asking an AI assistant through edit_note. Pictures posted with a note move with it.
• Breaking: the header for a note's time is now X-Note-Date, and a post that still sends X-Note-Created is refused with an error. Everywhere else it is date instead of created_at, createdAt or --created. The old names no longer work.
• Note ids are now random. Every existing note gets a new id and keeps its date, so links to single notes and their pictures stop working, and links from one feed to another are not updated. If you run notefeed yourself, back up your data and images before upgrading.

All the details are in the release notes and on GitHub.
