Description
I know it's a weird combo (no halting debug is rare), but if we read this from IPSR instead of ICSR we avoid the problem altogether.

Research direction
Start in macros/src/lib.rs around line 227, where the issue identifies the status read. Compare the current ICSR source with the proposed IPSR source and verify the behavior for armv8m-baseline without halting debug. Done means the problematic read no longer relies on the RES0 ICSR field and the project still builds successfully.
