/**
 * Handles the get_outgoing_meps MCP tool request.
 *
 * Retrieves Members of European Parliament who are departing parliament during the current
 * parliamentary term. Useful for monitoring political transitions, succession analysis, and
 * identifying final-engagement opportunities with outgoing stakeholders.
 *
 * @param args - Raw tool arguments, validated against {@link GetOutgoingMEPsSchema}
 * @returns MCP tool result containing a paginated list of outgoing MEP records for the
 *   current parliamentary term
 * @throws - If `args` fails schema validation (e.g., limit out of range 1–100)
 * - If the European Parliament API is unreachable or returns an error response
 *
 * @example
 * ```typescript
 * const result = await handleGetOutgoingMEPs({ limit: 20, offset: 0 });
 * // Returns up to 20 MEPs who are leaving the current parliamentary term
 * ```
 *
 * @security - Input is validated with Zod before any API call.
 * - Personal data in responses is minimised per GDPR Article 5(1)(c).
 * - All requests are rate-limited and audit-logged per ISMS Policy AU-002.
 * @since 0.8.0
 * @see {@link getOutgoingMEPsToolMetadata} for MCP schema registration
 * @see {@link handleGetCurrentMEPs} for all currently active MEPs
 * @see {@link handleGetIncomingMEPs} for MEPs who are newly joining parliament
