Replaces the external crate dependency with local code to avoid maintaining a separately published package for such a small, single-consumer library. Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com>
Temperatures were always empty because pfSense/OPNsense don't load the coretemp/amdtemp kernel modules by default, so the dev.cpu.N.temperature sysctls sysinfo reads never existed; now best-effort kldload them before polling starts. Disk read/written bytes were always zero on ZFS-rooted boxes (the modern pfSense/OPNsense default) because sysinfo attributes I/O by matching a /dev/... device path, but a ZFS root reports its source as a dataset name instead. Added a FreeBSD-only fallback that resolves the pool backing "/" via zpool status and reads GEOM's raw devstat counters for just its backing disks, avoiding double-counting from the partition/label layers stacked on top of each disk.

… work Replaces the hand-rolled per-platform socket enumeration (netinfo/sock) with the listeners crate, removing unshielded blocking Win32 syscalls on the async executor and a sequential /proc walk. Switches ItemBuffer to VecDeque and restructures the dump-file retransmission loop to avoid O(n^2) front-drains on large backlogs. Moves JSON (de)serialization and fireparse config parsing onto spawn_blocking so large payloads can't stall the shared tokio runtime. Also caches the config digest instead of re-hashing unchanged content each tick, parallelizes per-socket HTTP/SSH service probing, fixes a short-circuit bug in sysconfig's update_all, and trims a couple of small per-tick allocations in FreeBSD disk-IO and resource monitoring.

for_kv_map (iterate lock.values() instead of (_, v) in lock.iter()) and needless_borrow in wallguard-server, plus collapsible_if in the FreeBSD-only GEOM label-mapping parser (invisible to clippy on non-FreeBSD hosts). Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com>
