start cashu lib with bun tests

[gudnuf]

I started to create the cashu library we will need. This is in lib/cashu.

In types.ts I added types for proof secrets which I would appreciate feedback on. For now we are only using the P2PK secret but as we want to add advanced functionality like DLCs, we will be using these secrets a lot.

A secret can be a string (NUT00) or of the well-known secret format described in NUT10. For NUT10 secrets I created two types. There is the tuple type ParsedNUT10Secret that is what we get when we call JSON.parse(secret), and then I convert that to NUT10Secret which is easier to work with.

I also setup testing using bun. All that was needed was to add bun's types to the project

I'm getting this type error and I think it's because I added the bun types. Should we try to change the types in app/lib/timeout or figure out why adding bun types causes this error. Makes sense to me to use Bun's types for Timer instead of node types.

error TS2322: Type 'Timer' is not assignable to type 'number | Timeout | null'.
  Property '[Symbol.dispose]' is missing in type 'Timer' but required in type 'Timeout'.

I am not sure why it happens. Let's fix it by defining type like this:

type LongTimeout = {
  id: ReturnType<typeof setTimeout> | null; // Tracks the latest timeout ID
};

this way we are safe no matter the runtime

Nice! fixed
