Extends the guardrails suite with two built-in guardrails registered per
request (default_on=False, opted in via the chat body's guardrails selector)
so neither intercepts unrelated traffic on the shared proxy.
block_code_execution.pre_call.blocks: a python code block plus a run-this
request is intercepted with the canned content-blocked message and the model
never runs, while the same code block asked about with don't-run-it reaches
the model. Verified live.
openai_moderations.pre_call.blocks: a flagged prompt is rejected 400 naming
the moderation policy while a benign prompt passes. The guardrail calls
OpenAI's moderation API; verifying it needs an OpenAI key with moderation
quota (this account currently 429s the moderation endpoint).
Adds a shared create_backend_model helper and a generic register() plus
per-request guardrails/max_tokens on the client so more built-ins can reuse
the same path.
