This reduces confusion w/ types like `AgentState`, different arg names,
etc.
Second attempt, following
https://github.com/langchain-ai/langchain/pull/33249
* Ability to pass through `cache` and name in `create_agent` as
compilation args for the agent
* Right now, removing `test_react_agent.py` but we should add these
tests back as implemented w/ the new agent
* Add conditional edge when structured output tools are present to allow
for retries
* Rename `tracking` to `model_call_limit` to be consistent w/ tool call
limits
We need in the future (I'm happy to own):
* Significant test refactor
* Significant test overhaul where we emphasize and enforce coverage
- retry_model_request hook lets a middleware decide to retry a failed
model request, with full ability to modify as much or as little of the
request before doing so
- ModelFallbackMiddleware tries each fallback model in order, until one
is successful, or fallback list is exhausted

- supports 6 well-known PII types (email, credit_card, ip, mac_address,
url)
- 4 handling strategies (block, redact, mask, hash)
- supports custom PII types with detector functions or regex
- the built-in types were chosen because they are common, and detection
can be reliably implemented with stdlib
