Agent v2

[futursolo]

Description

This pull request consists of the following changes:

• Adapts the Worker v2 format.
• Agents are now managed via context providers.
• Adds Task Agent (For each agent a single input and a single output is expected)
• Adds Reactor Agent (For each agent, multiple inputs and multiple outputs are expected)
• SSR support for memorised Tasks.

This pull request needs the following pull requests:

• #2769
• #2772

Questions to solve:

• In Rust, a running asynchronous coroutine is also commonly named task. This may cause confusion to users. I do not have a better name for this, so I am open to suggestions to an alternative name than task.

Still missing:

• tests
• documentation

Checklist

• [x] I have reviewed my own code
• [ ] I have added tests

⚠️ The following example has changed its size significantly:

examples master (KB) pull request (KB) diff (KB) diff (%) web_worker_fib 153.862 180.933 +27.070 +17.594%

This is partially due to the migration from struct components to function components.

I have produced a copy from both the master branch and the agent-v2 branch with agent related code removed and the size has increased for about 13KB.

Still need to reduce on bundle size impact by the new agent design.

We should have a struct components example too

I think it is fine with without struct component examples. Just like the tutorial is switched to all function components, we should continue to promote users to use function components.

[futursolo]

I'm wondering if there's a way to have an async function that is run inside a worker and the result of it can be .awaited on the main thread?

Isn't that the oneshot worker / agent?
