OKX V5 API endpoint lookup

A router over the OKX V5 API docs. The site table, the routing index/, and the per-endpoint bodies all ship inside this skill's own directory — the same directory this SKILL.md lives in. The primary lookup flow is for REST endpoints: given a REST endpoint, it resolves the site's REST base URL/domain, whether that endpoint is supported on the target site, and which doc file holds the params/response/rate-limit details.

WebSocket Markdown can exist in the corpus as supplemental documentation. Search it when needed, but do not assume WebSocket docs have the same deterministic REST endpoint-path routing/index.

Everything is local and self-contained — no network at query time, and nothing to set up. npx skills add installs SKILL.md together with its data (sites.json, index.json, index/, docs/), all under this skill's directory.
