Fix remaining audit findings

[davegomez]

An audit against the Fizzy API docs found CardSchema silently dropped the plain text description field during Zod parsing, fizzy_search exposed only 6 of the 12 available query filters, and the boards tool had no pagination continuation test coverage.

CardSchema now accepts the optional description field alongside description_html. Six missing search filters — creator_ids, closer_ids, card_ids, assignment_status, creation, closure — thread through schema, client, and tool layers. A cursor-based pagination test verifies multi-page board fetches end-to-end. README updated to reflect the expanded parameter surface.

480 tests pass, lint and typecheck clean.

Greptile Overview

Greptile Summary

Fixed three audit findings against the Fizzy API: added missing description field to CardSchema, exposed 6 previously unavailable search filters (creator_ids, closer_ids, card_ids, assignment_status, creation, closure), and added cursor-based pagination test for boards.

• Added optional description field alongside existing description_html in CardSchema (src/schemas/cards.ts:48)
• Extended CardFiltersSchema with 6 new filter fields matching Fizzy API capabilities
• Threaded new filters through client query parameter building (src/client/fizzy.ts:450-466)
• Updated fizzy_search tool parameter schema and execute function to accept new filters
• Added comprehensive test coverage: schema validation tests for all new filters, parameter passing tests, and multi-page board pagination test
• Updated README to document all 12 search parameters with date range value reference

All changes follow existing patterns - array filters use append() for query params, single-value filters use set(), optional fields marked properly with Zod. Test assertions verify correct parameter serialization.

Confidence Score: 5/5

• Safe to merge - audit fixes with comprehensive test coverage
• All changes are additive (no breaking changes), follow established codebase patterns, have thorough test coverage including edge cases, and the PR reports 480 passing tests with clean lint/typecheck
• No files require special attention
