allow llmClient to be optionally passed in

[arihanv]

why

Allow users to easily define their own llm clients rather than adding support for each major provider in the main codebase #350

what changed

Added llmClient to Stagehand constructor so that custom clients can be passed in

[kamath]

this looks great! can we add an example of how to use a custom client (like in #349 with ollama/llama 3.2) in examples/? would love custom_client.ts that implements an LLMClient for Llama 3.2 using Ollama that can be passed in on init.

we also need to work towards a fast-follow PR that can allow a user to pass in a custom LLMClient to act/extract/observe as well

[arihanv]

#349 now proposes an example ollama client which extends the LLMClient and uses Llama 3.2.

[kamath]

Perfect, I think both look good -- can we add #349 here as follows:

• Move the Ollama Client to ./examples/external_clients/ollama.ts
• Create an example at ./examples/external_client.ts that references the LLMClient above

This way, we can more easily clone the branch and make sure nothing else is breaking. tysm 🙇 🙏

Also, please add a changeset (npx changeset) with a minor tag (since this changes the interface to the end user), and add any supplementary docs to the README

hell yeah! merging into an evals branch to make sure we're not missing anything

[kamath]

for future PR: we should make LLMClient default inherit logger from Stagehand so we don't have to do this
