On macOS, getrlimit(RLIMIT_NOFILE) can return RLIM_INFINITY (INT64_MAX). The
calculation fd_number / 100 * segment_cache_fd_percentage produces
1844674407370955160, which overflows cast_set<uint32_t> in SegmentCache
constructor, crashing BE on startup. Linux kernels cap this via fs.nr_open
(default 1M), so only macOS is affected.
Fix: cap fd_number on macOS before the segment cache capacity calculation.
