/**
* Handles the get_committee_info MCP tool request.
*
* Retrieves European Parliament committee (corporate body) information including
* composition, chair, vice-chairs, members, meeting schedules, and policy areas.
* Supports lookup by committee ID, abbreviation, or listing all current active bodies.
*
* @param args - Raw tool arguments, validated against {@link GetCommitteeInfoSchema}
* @returns MCP tool result containing committee details or a list of current active corporate bodies
* @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
* // Lookup by abbreviation
* const result = await handleGetCommitteeInfo({ abbreviation: 'ENVI' });
* // Returns detailed info for the Environment Committee
*
* // List all current active bodies
* const all = await handleGetCommitteeInfo({ showCurrent: true });
* // Returns all currently active EP corporate bodies
* ```
*
* @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 getCommitteeInfoToolMetadata} for MCP schema registration
* @see {@link handleGetCommitteeDocuments} for retrieving documents produced by committees
