LibreNMS reference checkout

A shallow clone lives at /home/svcuser/src/librenms (commit 06080bb3) for reference only. It is outside this repo. Set NMON_LIBRENMS_DIR to point tests and the importer at it.

Path	What it is	Used for
mibs/	4,865 MIBs (standard at the top level, vendors in subdirs)	copied into nmon/mibs/ (DEVIATIONS #6)
resources/definitions/os_detection/*.yaml (817)	OS matchers: sysObjectID, sysDescr, mib_dir	nmon-librenms-import (separate offline tool), the profile match: section
resources/definitions/os_discovery/*.yaml (708)	per-OS processors, mempools, storage, sensors with oid, num_oid, divisor, skip_values	the importer, and checking vendor OIDs in shipped profiles
tests/snmpsim/*.snmprec (2,054)	real device recordings	optional real-device fixture tests (DEVIATIONS #8)
LibreNMS/OS/*.php, includes/polling/	poller logic	reading only; the converter contains no LibreNMS code

LibreNMS is GPLv3. Nothing from it except the MIB files (which are third-party) is copied into nmon.
