Feature: Add prompt history

[danneu]

First of all, love the plugin. It's so simple. You don't wanna know how many times I've manually copy and pasted multiple files into an LLM chat to give it context for my prompt.

Feature:

Every time you click "Create context", it could save the prompt to a history list.

Clicking on history items will repopulate the UI with the prompt. Though v0.1 could be to just copy the prompt to clipboard with a small preview or something instead of, say, repopulating the checkbox states of the filetree.

Or clicking summons the vscode modal with the prompt in a text area. That way it doesn't even touch existing ui.

Why:

A common LLM issue in general is when you have some great prompt, use it a bit, move on to something else, but then lose the prompt. That prompt you spent time writing is all the way at the top of some chat scrollback or something.

I also desire more prompt reuse out of this.

Ok there is a snippets feature but this is an easier win and I'll start here.

@danneu this is rather late, but i have a simple version of this being published now.

1. I only store prefix/suffix for prompts. But it sounds like you would prefer a full save of like all selected files as well?

v1.6.0 is rolling out now with the history list of just the prompt. lmk if not enough
