refactor: load config with shared config loader package

[chenjiahan]

Summary

This PR switches Rstack config loading to @rstackjs/load-config so user config resolution can use the shared Rstack loader instead of the Rsbuild loader. It adds the package to the workspace catalog, keeps jiti external in the CLI bundle, and updates the spelling dictionary for the new package scope.

📝 Walkthrough

Walkthrough

This change adds @rstackjs/load-config as a new dependency, registering it in the pnpm workspace catalog with version ^0.1.1 and adding it to package.json devDependencies. The minimumReleaseAgeExclude list is extended to exempt @rstackjs/* packages. In packages/rstack/rslib.config.ts, an output.externals entry for jiti is added. In packages/rstack/src/config.ts, the RsbuildConfigDefinition import is separated into a type-only import. A custom dictionary entry rstackjs is added to scripts/dictionary.txt.

Preserve fresh config imports

Switching loadRstackConfig() to @rstackjs/load-config changes the cache behavior unless fresh: true is passed: the new loader defaults to reusing the native module cache, while the previous Rsbuild loader always bypassed it. Because loadRstackConfig() clears state.configs after each call, any second config load in the same CLI process, such as a dev-server restart/config reload, will not re-execute the user's define.* calls and will return an empty config. Please pass fresh: true in the loadConfig options to preserve the previous behavior.
