fix(cache): make in-memory and disk cache increments atomic (#34013)
* fix(cache): make in-memory and disk increments atomic

* refactor(cache): narrow in-memory increment lock scope

* fix(cache): address follow-up review on increment tests/types

* fix(cache): refresh atomic increment coverage

* test(cache): widen increment race window with non-zero _SlowInt seed

The zero seed was falsy, so InMemoryCache.increment_cache's `get_cache(...) or 0`
and DiskCache.get_cache's truthiness guard both discarded the _SlowInt before
__add__ could run, leaving the sleep-based window-widening inert. Seed a non-zero
value and return _SlowInt from __add__ so the sleep fires on every read-modify-write
in both backends, making the concurrency regression deterministic.

* test(cache): cover InMemoryCache.async_increment delegation

Add a focused async test asserting async_increment accumulates through the
locked sync path, exercising the previously uncovered delegation line.
