Regenerate OpenAPI docs for modelcontextprotocol/registry v1.7.2

The upstream `Package.Version` schema gained `maxLength: 255` (and the
skill `version` field gained `maxLength: 255` / `minLength: 1`) in
`modelcontextprotocol/registry` v1.7.0. Renovate's go.mod bump didn't
re-run `task docs`, so `docs/thv-registry-api/{docs.go,swagger.json,swagger.yaml}`
were stale and the `Verify Generated Files` job rejected the PR.

Run `task docs` to regenerate against v1.7.2 — no behavioral change,
only the OpenAPI schema reflects the upstream constraints.
