Pull request overview

This PR makes the thv llm command group part of the public CLI surface and regenerates the CLI reference so the LLM gateway workflow is documented alongside the rest of ToolHive. It also updates the top-level llm description to say proxy and token-helper modes are supported rather than planned.

Changes:

• Unhide thv llm and thv llm token in the Cobra command tree.
• Update the thv llm long description to describe supported proxy/token-helper modes.
• Regenerate docs/cli/ so the full thv llm command tree appears in CLI reference docs.

• runLLMToken returns an OAuth/OIDC access token, not necessarily a JWT. Some providers issue opaque bearer tokens, so documenting this as a "fresh JWT" is inaccurate and may lead users to build integrations that incorrectly depend on JWT structure.

authentication transparently. Two modes are supported:

  Proxy mode    — a localhost reverse proxy injects fresh tokens for tools
                  that only accept static API keys (e.g. Cursor).
  Token helper  — "thv llm token" prints a fresh JWT suitable for use as
                  apiKeyHelper or auth.command in OIDC-capable tools
                  (e.g. Claude Code).
