Juan Fernando Castro a9a8df6409 feat(events): fetch can start at the newest notification, and the feed uses it (#4479)
* feat(events): fetch can start from the newest event

GET /events/fetch takes from=end: with no cursor it answers an empty page
whose cursor sits at the newest row of the slice, so later reads return
only rows created or replaced after it. puter.events.fetch() passes
`from` through. Adds a (user_id, audience, app_uid, id) index on
notification so the newest row of a slice is one seek.

* fix(puter-js): onPush starts its feed from the newest notification

A notifications listener started without catch-up asks for from: 'end'
and keeps the cursor it gets back instead of reading every stored
notification to mark them as seen. A server that ignores `from` answers
with the oldest page, and the listener reads through it as before.

* fix(events): read the newest notification id from the primary

* fix(events): mark the end cursor at the slice's latest replacement

The end cursor's replacement mark is the newest (replaced_at, id) in the
slice rather than the serving node's clock, since replaced_at is stamped
by whichever node wrote it.

* docs(events): describe the end cursor's replacement mark

Getting Started

💻 Local Development

git clone https://github.com/HeyPuter/puter
cd puter
npm install
npm start

→ This should launch Puter at http://puter.localhost:4100

To run this checkout with Docker, follow Building from source. Create a local docker-compose.override.yml to select the local build; keeping these settings out of docker-compose.yml avoids conflicts when pulling updates and keeps local configuration out of pull requests.
