feat: add ai snippets

[gagik]

One can install this snippet using the snippet command in mongosh:

# Set your snippet sources
config.set('snippetIndexSourceURLs',  'https://github.com/gagik/mongosh-snippets/raw/refs/heads/ai/index.bson.br;' + config.get('snippetIndexSourceURLs'))
# Restart mongosh for the change to take effect.
# Install the ai snippet
snippet install ai
# Run `ai` to out the commands!
ai

Keep in mind that this package-lock file has no practical effect 🙂

This isn't ready to merged, pending better alignment with product, but feel free to try it out!

might be worth adding a basic "locking" mechanism to prevent something like

for (var i = 0; i < 10; i++) { ai.ask("what is mongosh?") } 

That said I also find the idea of something like const a = ai.generate("sample document") function quite cool, albeit as thing stands pretty wasteful

I wouldn't fully discount this as an option, with a local model this would actually be pretty much just fine, right?

[gagik]

yeah, that said if they're using their own API key, it also poses a risk of accidentally getting them to spend a lot of money.
I can turn this into a configurable option and have it set to only 1 request at a time by default.

For now, this is kind of true for all snippets we have

[addaleax]

Can we have a ticket in mongosh to provide stdin, stdout, stderr streams in mongosh instead of having snippets work with process.* directly? mongosh is generally built in a way where it's not necessarily true that the streams that mongosh reads from and writes to are the process-wide stdio streams, and I'd prefer not to hardcode that expectation in snippets if we don't need to
