/**
* Handles the get_current_meps MCP tool request.
*
* Retrieves Members of European Parliament who hold an active mandate as of today's date.
* Outgoing or inactive members are excluded, providing a real-time snapshot of the current
* parliamentary composition.
*
* @param args - Raw tool arguments, validated against {@link GetCurrentMEPsSchema}
* @returns MCP tool result containing a paginated list of currently active MEP records
* @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 handleGetCurrentMEPs({ limit: 50, offset: 0 });
* // Returns up to 50 MEPs with active mandates as of today
* ```
*
* @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 getCurrentMEPsToolMetadata} for MCP schema registration
* @see {@link handleGetIncomingMEPs} for MEPs who are newly joining parliament
* @see {@link handleGetOutgoingMEPs} for MEPs who are departing parliament
