Move PNG/JPEG/BMP/GIF/WEBP parser implementations out of index.ts into dedicated files under packages/napcat-image-size/src/parser. Export ImageParser and matchMagic from index.ts, import the new BmpParser, GifParser, JpegParser, PngParser and WebpParser classes, and update the parsers array to instantiate those classes. Keeps existing parsing logic and stream-based size detection while cleaning up index.ts for modularity.
* feat: pnpm new
* Refactor build and release workflows, update dependencies
Switch build scripts and workflows from npm to pnpm, update build and artifact paths, and simplify release workflow by removing version detection and changelog steps. Add new dependencies (silk-wasm, express, ws, node-pty-prebuilt-multiarch), update exports in package.json files, and add vite config for napcat-framework. Also, rename manifest.json for framework package and fix static asset copying in shell build config.
