* MCP Tool: get_procedures
*
* Retrieve European Parliament legislative procedures.
* Supports single procedure lookup by processId or list with year filtering.
*
* **Intelligence Perspective:** Procedure data enables end-to-end legislative tracking,
* outcome prediction, and timeline analysis—core for policy monitoring intelligence.
*
* **Business Perspective:** Procedure tracking powers legislative intelligence products,
* regulatory risk assessments, and compliance early-warning systems.
*
* **EP API Endpoints:**
* - `GET /procedures` (list)
* - `GET /procedures/{process-id}` (single)
*
* ISMS Policy: SC-002 (Input Validation), AC-003 (Least Privilege)

/**
* Handles the get_procedures MCP tool request.
*
* Retrieves European Parliament legislative procedures enabling end-to-end legislative
* tracking, outcome prediction, and timeline analysis. Supports both a single-procedure
* lookup by `processId` and a paginated list optionally filtered by year.
*
* @param args - Raw tool arguments, validated against {@link GetProceduresSchema}
* @returns MCP tool result containing procedure data (single procedure or paginated list)
* @throws - If `args` fails schema validation (e.g., invalid field types or formats)
* - If the European Parliament API is unreachable or returns an error response
*
* @example
* ```typescript
* // Single procedure lookup
* const single = await handleGetProcedures({ processId: '2023/0132(COD)' });
* // Returns the legislative procedure for the Artificial Intelligence Act
*
* // List procedures from 2024
* const list = await handleGetProcedures({ year: 2024, limit: 50, offset: 0 });
* // Returns up to 50 legislative procedures initiated in 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 getProceduresToolMetadata} for MCP schema registration
* @see {@link handleGetProcedureEvents} for retrieving events linked to a specific procedure
