Summary

• Channels with a lot of people coming and going filled up with join and leave notices. The app started a new notice line every time the activity switched between joining and leaving, every new day, and after every quiet hour. Busy channels stacked dozens of these lines between real messages, so readers had to scroll a long way to get back to where they had stopped reading.
• Now, a stretch of join and leave activity that has no message in it shows as at most two lines: one for the people who arrived and one for the people who left. Each person shows once, on the line that matches their last change, so the two lines tell you who is in the channel after the stretch. Only a real message starts a new stretch.

Details

• Arrivals line: joins and additions. It reads "joined", "added by X", or "arrived" when the stretch has both.
• Departures line: leaves and removals. It reads "left the channel", "was removed by X", "was removed" when different people removed members, or "departed" when the stretch has both leaves and removals.
• Each person appears once, described by their latest change in the stretch. Joined → left → joined reads "Pinky joined"; joined → left reads "Pinky left the channel". The old "joined and left the channel" wording is gone. All of a person's changes stay attached to their line, so a saved reading position on any of them still finds its line.
• The line that holds the stretch's first change comes first, and each line sits under the day of its oldest change. Each line keeps the identity of its newest change, so loading older history makes a line longer without replacing it. When an older page brings in an earlier change of the other kind, the two lines swap places; a test covers this.
• Code: membershipRows and membershipDescription in src/features/messages/membership-rows.ts. The browser test tests/browser/membership.spec.mjs now expects a removal to merge into the existing departures line.
