build: add ndk with svelte add-ons

consideration was given to using a shared library built in rust
for this and the cli utility but this was discounted for these
reasons:

1. different data storage and caching requirements
2. ndk is more mature and has extra features for building web
   apps
3. use of shared svelte components in ndk
4. prospect of contributing git specific components to ndk to
   encourage adoption among other clientus
