feat(KB-330): rename internal packages from @kb/* to @fusion/*

- Rename @kb/core, @kb/dashboard, @kb/engine to @fusion/* namespace - Update all import statements across 143+ files to use new package names - Update workspace dependencies and root package.json references - Fix bundler configurations (tsup, vite) for new package names - Update test files and fix typecheck issues - Add changeset file documenting the package rename
