/**
* Handles the get_plenary_session_documents MCP tool request.
*
* Retrieves European Parliament plenary session documents such as agendas, minutes, and
* voting lists. Supports both single-document lookup by document ID and paginated list
* retrieval. Core data source for parliamentary activity monitoring and meeting intelligence.
*
* @param args - Raw tool arguments, validated against {@link GetPlenarySessionDocumentsSchema}
* @returns MCP tool result containing either a single plenary session document (when `docId`
* is provided) or a paginated list of session documents including agendas, minutes, and
* voting lists
* @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
* // List the most recent session documents
* const result = await handleGetPlenarySessionDocuments({ limit: 10, offset: 0 });
* // Returns up to 10 plenary session documents (agendas, minutes, voting lists)
*
* // Fetch a single session document by ID
* const single = await handleGetPlenarySessionDocuments({ docId: 'SESS-DOC-2024-042' });
* // Returns the full session document record
* ```
*
* @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 getPlenarySessionDocumentsToolMetadata} for MCP schema registration
* @see {@link handleGetPlenarySessions} for the sessions these documents belong to
* @see {@link handleGetPlenaryDocuments} for broader legislative plenary documents
