using svelte format for stories requires storybook to run with the
--index-json flag but this breaks the storage location of DOM
snapshots
the configuration files in this commit fixes this and also moves them
to the same location as the image snapshots
add image and dom snapshot comparison for storybook components
image snapshot comparison can been flaky and produce many
false-positives. a higher threshold has been used to mitigate this
although it may not identify all regressions. DOM snapshots
supplement images to increase the likelihood of capturing
regressions.
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
start with a nix boilerplate for svelte that supports reproducible
builds
