Revise the awaitAll methods and others according to the principle of least astonishment.

Renaming await Functions for Better Semantics

Problem

The current function names awaitAll() and awaitAllWithErrors() are misleading:

• awaitAll() sounds like “wait for all,” but actually cancels all coroutines on the first error.
• awaitAllWithErrors() has safer behavior but is hidden behind a longer name.
• It violates the principle of least surprise.
• Unsafe default behavior may lead to resource loss in production.

Goal

Make the API more intuitive and safe by default, renaming functions so that:

1. Simple names provide safe (fail-safe) behavior.
2. More complex names require an explicit choice of unsafe (fail-fast) behavior.
3. Names accurately reflect the actual function behavior.
