…Linux PUMA's REGULATION struct array with MAXTFS=1500 creates a ~2GB __DATA segment that exceeds the macOS Mach-O segment size limit, causing dyld to fail loading libc++.1.dylib/libSystem.B.dylib with exit code 134 (SIGABRT). Reducing MAXTFS and MAXMIRS to 1000 (matching PANDA) brings __DATA under the limit. Output is verified identical with the toy dataset reference.

Problem
CI fails on both ubuntu-latest and macos-latest with exit code 134 (SIGABRT) when running PUMA.
Root cause: PUMA REGULATION struct array with MAXTFS=1500 creates a ~2 GB __DATA segment that exceeds the macOS Mach-O segment size limit. This causes dyld to fail loading shared libraries (libc++.1.dylib, libSystem.B.dylib), aborting the process before main() even runs.
Fix
Reduce MAXTFS and MAXMIRS from 1500 back to 1000 (matching PANDA). This brings the __DATA segment from ~2.0 GB to ~1.83 GB, within limits.
