docs(auto_routing): host an interactive auto router setup skill and link to it

[devin-ai-integration]

Summary

Gives the auto routing page a one-line way to get started, following the pattern OpenRouter uses for Ori Eval: the docs carry the command and nothing else, and the instructions live in a file the agent fetches.

run curl -fsSL https://docs.litellm.ai/skills/auto-router and follow the instructions

The skill body is static/skills/auto-router (extensionless, served verbatim like the existing llms.txt). It is an interview, not a script. The agent enumerates the models the proxy already serves (from the loaded config or /v1/models), then asks the user for the router name and for the model behind each of SIMPLE, MEDIUM, COMPLEX, and REASONING plus the classification fallback, with an explicit instruction not to propose a name or pre-fill an assignment. It then writes a single auto_router/complexity_router entry, or the /model/new equivalent on a DB-managed proxy.

Before finishing it has to lay out the defaults left in force as a table (heuristic classifier, session affinity off, no keyword rules, no semantic matching, adaptive off, built-in technical keywords, built-in scorer thresholds) with what changing each one buys, ask whether the user wants any of them changed, and keep unchanged values out of the config so the backend default applies. Choosing the LLM classifier surfaces its own defaults, classifier_context_window_size: 3 and classifier_context_per_turn_chars: 200 with assistant turns excluded, as another decision rather than a silent one.

Wording stays agent-neutral throughout; the Anthropic-shaped name rule appears only as a conditional aside for clients that filter model names by vendor, and the Claude Code tutorial points at the same command.

Verified with npm run build, then served the build and confirmed GET /skills/auto-router returns 200 with the file body.
