Migrate to crafter-build project.cpp and restructure views

- Replace project.json + run.sh with a C++ project.cpp build descriptor
  (crafter-build), targeting wasm32-wasip1 with the Crafter.Graphics dep
- Add Catcrafts-Views implementation; drop Catcrafts-Component
- Add catcrafts-head.js (sets <title>/<link> tags at runtime)
- Update Blog/Root/main modules, README, and favicon
