The buses I've seen are still capable of going under their own power, and they can easily attach/detach from the wires: https://www.youtube.com/watch?v=9k1z10U3utc
So detours and overtakings are no big deals.

What about an hybrid solution? Smaller batteries could let trolleybuses venture from their infrastructure as needed, but at a reduced cost.

We had this here in the Netherlands, the system broke down quite a lot and apparently had quite some wear and tear
I guess it can be improved thoug.

How do they re-attach the bus to the power lines? Is it reasonably automatic, or does the driver have to fuss with it?

It's not an overreach, trolleybuses work surprisingly well at the moment. Lighter, much, much cheaper, less electricity required. And you need less of them.
Metro, trams, trolleybuses should be used primarily and then you can add electric buses for gaps. That would make sense, not trying to go straight for the most expensive and wasteful option.

How can they be cheaper? You still need to install all the overhead wiresm this only works if you assume they the routes never change. And will require an absurdly huge initial investment. Might be better/cheaper to just see if batteries get better or if more quick charge points can he installed.

The vehicules are have less components thus are both cheaper upfront and cheaper on at operation by being lighter and requiring less maintainance. Because of that they are on average bigger so you can have a smaller fleet. Also installing overhead cables isn't such a big investment (in the face of related urban investment needed anyway like road maintainance, street furnitures and traffic/lanes shaping). Remember that tons of cities install christmas decorations with similar overhead wires just for one month every year.
It's also, I would guess, a lot more difficult to get off the ground. With battery powered buses, you just buy however many buses, and throw them on whatever pre-existing route. With a trolleybus, you need to install the overhead wire system before you can get started.
And then, I would imagine the overhead wire system itself becomes a problem. Do you have to worry about transporting oversize loads on or across the same streets? Is it going to become another electrocution hazard for people who need to work above the street? etc.
That's not to say there aren't advantages to trolleybuses, too. Just that the claim that it's "in every way superior to batteries" is an overreach.
