Consider including transitive dependencies in parent tasks

[PeterJCLaw]

For example comp/ops/main (e.g: srobo/tasks#543, though note that that has been manually adjusted to fix this) depends on comp/venue/network (e.g: srobo/tasks#419), though finding the latter when considering the former is non-obvious.

It might be the case that we just need to get better at doing this explicitly in the repo for cases where it makes sense, though it might also be worth doing it automatically.

There are definitely cases (e.g: at least root tickets) where this is less useful, so making this something that tickets can opt into or out of might also be useful.
