feat(gemini): add file import capability

This commit introduces the `doImport` function, which allows importing
the content of a file directly into the "auto" chat session.

The imported content is added as a `ChatEntry` from GEMINI, structured
as a `ToolCall` with the name "Shell" and the file content as the input.
This allows external command outputs to be seamlessly integrated into
the chat history for context.
