feat: add JSON input support for biological sequences

Introduce a streaming JSON parser that decodes biological sequences using `goccy/go-json` with configurable batching to minimize memory overhead. Extend the CLI, file suffix filters, and MIME type detection to automatically recognize and route JSON inputs. Refactor header parsing into a centralized switch-case handler for improved maintainability.
