docs(pricing-may-2026): reframe custom inference endpoint intro to lead with powering Warp's agents

Mirror the BYOK page's intro pattern so it's explicit upfront that a
custom inference endpoint is used to power Warp's agents. New opening:

  Warp supports custom inference endpoints for users who want to power
  Warp's agents with any OpenAI-compatible inference endpoint \u2014 a
  model router, hosted gateway, or internal infrastructure they
  already run.

  This lets you route AI requests through your preferred provider, run
  inference behind your own gateway, or use a router like OpenRouter
  or LiteLLM, while keeping the agent experience inside Warp.

No other changes.
