Support Amazon Q Developer IDE/CLI

[ymhiroki]

I use Amazon Q Developer CLI qchat and Amazon Q Developer IDE on a daily basis in addition to other already supported AI coding agents.

I would like this kit to support Amazon Q Developer CLI.

Hi, Den. Thank you for your assignment!
I tried to implement this request; however, Amazon Q Developer doesn't seem to have sufficient features such as custom slash commands or custom prompts.

I've created two issues for Amazon Q Developer IDE (VSCode toolkit) and Amazon Q Developer CLI.

Amazon Q Developer CLI will support the /prompts command for local prompts once this Pull Request is merged.
