Introduce a TIFF parser and integrate it into the image detection/size parsing pipeline. Add buffer-based APIs (detectImageTypeFromBuffer, imageSizeFromBuffer, imageSizeFromBufferFallBack) and a helper to convert Buffer to a Readable stream; refactor parser registry into a type-to-parser map and a first-byte fast-path map for quicker detection. Harden WebP parsing with safer length checks. Add sample image resources and a comprehensive Vitest test suite (packages/napcat-test) with updated package dependency and resolve aliases. pnpm-lock updated to link the new package.
