* Handles the get_meeting_activities MCP tool request.
*
* Retrieves activities linked to a specific European Parliament plenary sitting,
* such as debates, votes, and presentations. Requires a sitting identifier.
*
* @param args - Raw tool arguments, validated against {@link GetMeetingActivitiesSchema}
* @returns MCP tool result containing a paginated list of activities for the specified plenary sitting
* @throws - If `args` fails schema validation (e.g., missing required `sittingId` or invalid format)
* - If the European Parliament API is unreachable or returns an error response
*
* @example
* ```typescript
* const result = await handleGetMeetingActivities({ sittingId: 'PV-9-2024-01-15', limit: 20 });
* // Returns up to 20 activities from the specified plenary sitting
* ```
*
* @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 getMeetingActivitiesToolMetadata} for MCP schema registration
* @see {@link handleGetMeetingDecisions} for retrieving decisions from the same sitting
