Having said that, though, other times it will happily return results for the entire world in one go?

It depends on several things (query complexity, amount of data, how overpass is implemented,
probably also load on servers).

You may be doing something wrong if you write own queries that can be optimized better.

It is likely not a laptop limitation (unless it fails during data rendering).

Note that timeout can be modified - "[timeout:25]" can be changed to say "[timeout:250]"
or even greater value

If you are interested solely in how many objects are with given area:

"out body;
out skel qt;"

"out count;"

and switch to data tab after query completes with special warning.

You an also remove say
"  node["landuse"="yes"]({{bbox}});"
line, if you do not care about nodes (the same for ways and relations)
