/**
* Handles the get_events MCP tool request.
*
* Retrieves European Parliament events including hearings, conferences, and seminars.
* Supports single event lookup by eventId or a paginated list filtered by date range.
*
* @param args - Raw tool arguments, validated against {@link GetEventsSchema}
* @returns MCP tool result containing either a single event record or a paginated list of EP events
* @throws - If `args` fails schema validation (e.g., missing required fields or invalid format)
* - If the European Parliament API is unreachable or returns an error response
*
* @example
* ```typescript
* // Single event lookup
* const result = await handleGetEvents({ eventId: 'EVT-2024-001' });
* // Returns the full record for the specified event
*
* // List events within a date range
* const list = await handleGetEvents({ dateFrom: '2024-06-01', dateTo: '2024-06-30', limit: 30 });
* // Returns up to 30 EP events in June 2024
* ```
*
* @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 getEventsToolMetadata} for MCP schema registration
* @see {@link handleGetMeetingActivities} for retrieving activities within a specific plenary sitting
