fix guide examples and add types package readme

refactor(tsconfig): move back base tsconfig to base directory

Create dedicated Typescript "types" configuration file for each "projects".
Create a types folder which includes every useful ts definition:
- client
- server
- shared
Add tooling to create a proper package, extract dependencies, etc...
Add CI Github task.

refactor(types): publish types package in release script

Many files from the `shared` folder were importing files from the `server` folder.
When attempting to use Typescript project references to describe dependencies,
it highlighted a circular dependency beetween `shared` <-> `server`.

The Typescript project forbid such usages.
Using project references greatly improve performance by rebuilding only
the updated project and not all source files.

Because --files does not work

In favour of HLS

We'll use it as cache in the future.

you don't have pending job anymore.
