/**
* Handle the `get_meeting_plenary_session_documents` MCP tool request.
*
* Retrieves all plenary session documents associated with a specific EP plenary
* sitting by calling `GET /meetings/{sitting-id}/plenary-session-documents` via
* {@link epClient}. The raw API response is normalised into a standardised
* {@link ToolResult} using {@link buildToolResponse}.
*
* @param args - Raw tool arguments provided by the MCP client. Must conform to
* {@link GetMeetingPlenarySessionDocumentsSchema}:
* - `sittingId` (string, required): EP plenary sitting identifier.
* - `limit` (number, optional): Maximum results to return (1–100, default 20).
* - `offset` (number, optional): Pagination offset (default 0).
* @returns A promise that resolves to an MCP {@link ToolResult} containing the
* plenary session documents for the requested sitting.
* @throws If `args` fails {@link GetMeetingPlenarySessionDocumentsSchema} validation
* (e.g. missing required `sittingId` or out-of-range `limit`).
* @throws If `sittingId` contains path-traversal characters (`.`, `\`, `?`, `#`)
* — the underlying client throws an `APIError(400)`.
* @throws If the European Parliament API is unreachable or returns an error response.
*
* @example
* ```typescript
* const result = await handleGetMeetingPlenarySessionDocuments({
* sittingId: 'PV-9-2024-04-22',
* limit: 20,
* offset: 0
* });
* // Returns plenary session documents for sitting PV-9-2024-04-22
* ```
*
* @security Input is validated with Zod before any API call.
* `sittingId` is checked against path-traversal characters before URL construction.
* 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 1.0.0
* @see {@link getMeetingPlenarySessionDocumentsToolMetadata} for MCP schema registration
* @see {@link handleGetMeetingPlenarySessionDocumentItems} for individual agenda-item documents
* @see {@link handleGetMeetingForeseenActivities} for planned meeting activities
