/**
* Handles the get_speeches MCP tool request.
*
* Retrieves European Parliament plenary speeches and debate contributions.
* Supports single speech lookup by speechId or a filtered list by date range.
*
* @param args - Raw tool arguments, validated against {@link GetSpeechesSchema}
* @returns MCP tool result containing either a single speech record or a paginated list of speeches
* @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
* // Single speech lookup
* const result = await handleGetSpeeches({ speechId: 'SPEECH-2024-001' });
* // Returns the full record for the specified speech
*
* // List speeches with date filter
* const list = await handleGetSpeeches({ dateFrom: '2024-01-01', dateTo: '2024-03-31', limit: 50 });
* // Returns up to 50 speeches from Q1 2024
* ```
*
* @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 getSpeechesToolMetadata} for MCP schema registration
* @see {@link handleGetMeetingActivities} for retrieving broader meeting-level activities
