/**
* Handles the get_procedure_events MCP tool request.
*
* Retrieves the chronological timeline of events (committee hearings, plenary debates,
* votes, and other milestones) linked to a specific EP legislative procedure, supporting
* precise legislative tracking and compliance monitoring.
*
* @param args - Raw tool arguments, validated against {@link GetProcedureEventsSchema}
* @returns MCP tool result containing the ordered list of events for the specified procedure
* @throws - If `args` fails schema validation (e.g., missing required `processId`)
* - If the European Parliament API is unreachable or returns an error response
*
* @example
* ```typescript
* const result = await handleGetProcedureEvents({
* processId: '2023/0132(COD)',
* limit: 50,
* offset: 0
* });
* // Returns committee hearings, plenary debates, and votes for procedure 2023/0132(COD)
* ```
*
* @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 getProcedureEventsToolMetadata} for MCP schema registration
* @see {@link handleGetProcedures} for retrieving the parent procedure record
