Restored previous conversation history.

Sometimes files don't seem to be created, even though the LLM seemed to use the correct format. This may be because the "Add file to chat" feature caused the "create new file" to be ignored.

Below is an example of this; I had a file called languagedb/PUBLIC_API.md describing the languagedb package. I wanted to make a similar file in storehouse/PUBLIC_API.md for the storehouse package. The LLM seemed to do the right thing to create the file; but aider asked me if I wanted to add the other file to the chat and (not thinking) I said yes; and in the end the original file wasn't added.

Below is the full chat, with the full contents elided.

> Can you create a storehouse/PUBLIC_API.md that summarizes the key public interfaces in this package, so you can effectively use this package's functionality without needing to include the implementation?

I'll create a PUBLIC_API.md file that summarizes the key public interfaces of the storehouse package:

storehouse/PUBLIC_API.md

languagedb/PUBLIC_API.md
Add file to the chat? (Y)es/(N)o/(D)on't ask again [Yes]:
The storehouse/PUBLIC_API.md file looks comprehensive and well-structured. It covers all the key public interfaces including:

 • Core types and error handling
 • Configuration management
 • Storehouse lifecycle (open/close)
 • Language and user management
 • Database connection caching
 • Schema management
 • Litestream integration
 • Directory structure documentation
 • Usage patterns with examples

I don't see any other files that need to be added to complete this documentation. The PUBLIC_API.md file effectively summarizes the storehouse package's functionality without exposing implementation details, making it easy for developers
to understand and use the package.
