fix(console): fix udev symlink naming bug + add portable audit tooling

Console fix: generate-config.sh wrote SYMLINK+="console/$name" (singular)
but ser2net.yaml opens /dev/consoles/$name (plural). They never matched,
so after every reboot the console ports failed until setup.sh's manual
fallback re-created the symlinks. Fixed the udev rule to use "consoles/"
to match ser2net and the README.

New portable read-only audit tools (AGPLv3-friendly, config-driven):
- perf/scripts/probe-storage.sh: disk/mount/export/SMART/storage.cfg probe
- perf/scripts/probe-network.sh: NIC/bond/LLDP/NFS/nconnect probe
- perf/scripts/conman-console.py: PTY-based conman console driver (replaces
  the old sw-capture.py that conflicted with ser2net)
- perf/scripts/snmp-switch-audit.py: SNMP-based switch inventory (interfaces,
  LLDP, LAG, VLANs) via pysnmp or net-snmp

Removed stale pre-conman switch tooling (sw-capture-remote.sh, sw-capture.py,
sw-probe.sh, sw-conman-probe.sh) and old .cmds files. Added fresh .cmds
files for the two cross-rack trunk endpoint switches.
