Tools need a configuration mechanism

[simonw]

Some tools need configuration. The sqlite tool needs to know the path to the database file for example - and maybe needs to support being instantiated multiple times against different databases? I solved that in https://github.com/simonw/llm-tools-sqlite first alpha by loading all databases in the current directory but it's a nasty hack.

I have a design for this now, implementing it here:

• Class mechanism allowing related tools to be bundled and configured #1059

Re-opening because this is not yet documented.
