Active, Archived, and Lost sessions

Every session falls into one of three categories, each with its own filter chip and a live count above the list:

• Active — a normal, current session.
• Archived — a session you archived in Claude. It's still fully readable here; the tag just reflects its status.
• Lost — a Windows transcript that has no matching Claude Desktop entry. Because the entry is what normally holds the title, a lost session has no stored title, so the app recovers one from the first message in the conversation. Without this, a lost session would have no title to list it under and would be invisible.

The three chips show or hide each category as you hunt for a conversation, and their counts reflect whatever sources are currently shown. An entry that was recovered this way also carries a Lost tag of its own — read it as "the title here was reconstructed, not the original."
