Log prompts and responses to SQLite

[simonw]

This is the feature I built llm for. I want to log my interactions to a SQLite database.

I'm going to have this work by saying "if ``/.llm/log.db` exists, log messages to that database".

Later on I may come up with more advanced ways of configuring this.

It will default to logging - provided that DB exists already - but there will be a command line option for "don't log".

A llm init-db command will create the database for you if it does not exist yet.

New docs:

Logging to SQLite

If a SQLite database file exists in ~/.llm/log.db then the tool will log all prompts and responses to it.

You can create that file by running the init-db command:

llm init-db

Now any prompts you run will be logged to that database.

To avoid logging a prompt, pass --no-log or -n to the command:

llm 'Ten names for cheesecakes' -n
