* MCP Tool: get_adopted_texts
*
* Retrieve European Parliament adopted texts (legislative resolutions,

* Supports single document lookup by docId or list with year filtering.
*
* **Intelligence Perspective:** Adopted texts represent final legislative outputs—
* tracking them enables assessment of legislative productivity and policy direction.
*
* **Business Perspective:** Adopted text monitoring powers regulatory compliance
* products and legislative change management services.
*
* **EP API Endpoints:**
* - `GET /adopted-texts` (list)
* - `GET /adopted-texts/{doc-id}` (single)
*
* ISMS Policy: SC-002 (Input Validation), AC-003 (Least Privilege)

/**
* Handles the get_adopted_texts MCP tool request.
*
* Retrieves European Parliament adopted texts, including legislative resolutions,
* first-reading positions, and non-legislative resolutions. Supports single document
* lookup by docId or a paginated list optionally filtered by year.
*
* @param args - Raw tool arguments, validated against {@link GetAdoptedTextsSchema}
* @returns MCP tool result containing either a single adopted text or a paginated list of adopted texts
* @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 adopted text lookup
* const result = await handleGetAdoptedTexts({ docId: 'P9-TA(2024)0001' });
* // Returns the full record for the specified adopted text
*
* // List adopted texts from 2024
* const list = await handleGetAdoptedTexts({ year: 2024, limit: 50 });
* // Returns up to 50 adopted texts from 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 getAdoptedTextsToolMetadata} for MCP schema registration
* @see {@link handleGetPlenarySessionDocumentItems} for retrieving in-session document items
