/**
* 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
