Refresh the current session token

POST
/v1/auth/refresh
curl --request POST \
  --url https://example.com/v1/auth/refresh \
  --header 'Authorization: Bearer <token>'

Requires a session token (kgi_sk_*); bearer tokens are managed via /v1/tokens. When the deployment wired a refreshToken callback and the provider issued a refresh token, provider tokens rotate too; otherwise only the framework session token rotates. OAuth 2.1 BCP refresh-token rotation: the OLD session token is invalidated (marked rotated) — reusing it after refresh returns 401 refresh-token-invalid so compliant clients can retry with the fresh token instead of prompting a re-auth.
