[Feat]: Add ability to attach entire folders to context.

[samyakkkk]

Describe the problem and solution that you'd like.

Currently, we can attach individual code snippets to text field in Dash Panel. It would also be helpful to have the ability to attach entire folders.

By default, they use the normal Gemini 1.0 PRO APIs. But if context limit goes beyond, we can also leverage 1.5PRO APIs.

Describe alternatives that you have considered.

Alternative solution right now is to attach every file of the folder individually which ain't the best experience.
