/**
* Handles the get_parliamentary_questions MCP tool request.
*
* Retrieves European Parliament questions (written and oral) submitted by MEPs,
* with optional single-question lookup by docId or list filtering by type, author,
* topic, status, and date range.
*
* @param args - Raw tool arguments, validated against {@link GetParliamentaryQuestionsSchema}
* @returns MCP tool result containing either a single question record or a paginated list of parliamentary questions
* @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
* // List answered written questions on climate policy
* const result = await handleGetParliamentaryQuestions({
* type: 'WRITTEN',
* status: 'ANSWERED',
* topic: 'climate policy',
* limit: 20
* });
* // Returns up to 20 answered written questions matching the topic
*
* // Single question lookup
* const single = await handleGetParliamentaryQuestions({ docId: 'E-000001/2024' });
* // Returns the full record for the specified question
* ```
*
* @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 getParliamentaryQuestionsToolMetadata} for MCP schema registration
* @see {@link handleGetVotingRecords} for retrieving plenary voting data
