register dependencies for injection

How to

• Register factories on the Route (via constructor deps=[...]) or via plugin mechanisms; inject by type in endpoint signature.
• Use async generators to manage per-request resources (open/yield/close).

Example

from ididi import NodeConfig
from sqlalchemy.ext.asyncio import AsyncEngine, AsyncConnection
from lihil import Route

async def get_conn(engine: AsyncEngine) -> AsyncConnection:
    async with engine.begin() as conn:
        yield conn

users = Route("/users", deps=[(get_conn, NodeConfig(reuse=False))])

@users.post
async def create_user(conn: AsyncConnection) -> dict:
    # use conn
    return {"ok": True}
