* Handles the generate_report MCP tool request.

*
* @param args - Raw tool arguments, validated against {@link GenerateReportSchema}
* @returns MCP tool result containing a structured report with summary, sections,
* statistics, and recommendations appropriate to the requested report type
* @throws {ZodError} If `args` fails schema validation (e.g., missing required fields or invalid format)
* @throws {Error} If the European Parliament API is unreachable or returns an error response
*
* @example
* ```typescript
* const result = await handleGenerateReport({

* subjectId: 'MEP-124810',
* dateFrom: '2024-01-01',
* dateTo: '2024-12-31'

* // Returns MEP activity scorecard with voting discipline, attendance,
* // committee contributions, and performance recommendations
* ```
*
* @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.
