What
On macOS, the check that retires background work under memory pressure no longer loads a system library to call sysctlbyname; it uses Bun's memory pressure API and retires at critical pressure. Failures now log a warning rather than throwing.
Details
Normal, warning and critical pressure map to levels 1, 2 and 4.
Other platforms are unchanged: free memory is compared against a threshold that defaults to 1024 MB when no server value is set.

Strings lifted out of the shipped bundle, so the claim above can be checked against them.
