Add development config files and wiring to include them in the shell build. Creates packages/napcat-develop/config/.env and packages/napcat-develop/config/onebot11.json, adds a root script `build🐚config` that builds napcat-shell and then runs napcat-develop's `copy-env` script. Update packages/napcat-develop/package.json to add the `copy-env` script (uses xcopy to copy config into the napcat-shell dist), tidy exports and metadata. This ensures dev configuration is packaged into napcat-shell during the build process.
Changed package.json main and exports to use index.js instead of index.cjs. Updated tsconfig.json to allow JavaScript files and expanded include patterns to support both JS and TS files.
Introduces the napcat-develop package with its own package.json and tsconfig.json. Updates build and dev scripts in the root package.json, modifies loadNapCat.cjs to adjust paths and output directories, and updates nodeTest.ps1 to use the correct script path.
