huskies: rename project from storkit to huskies

Rename all references from storkit to huskies across the codebase:
- .storkit/ directory → .huskies/
- Binary name, Cargo package name, Docker image references
- Server code, frontend code, config files, scripts
- Fix script/test to build frontend before cargo clippy/test
  so merge worktrees have frontend/dist available for RustEmbed
