Fix naming to use the more generic AGENTS.md context file

The updated standard [1] uses a plural name `AGENTS.md` and we can add a
Gemini CLI settings file to point to it as the context file, removing
the need for a `GEMINI.md`. This change moves the little bit of
non-duplicate content from GEMINI.md into AGENTS.md and then removes it.

Tweak the gitignore rules to allow committing the .gemini/settings.json
with that context.fileName setting.
