Adds a `raid` mode that surfaces Synology raid status (OID 1.3.6.1.4.1.6574.3.1.1.x) for every storage pool: Normal → OK, intermediate states (Repairing/Migrating/Expanding/.../Canceling) → WARNING, Degrade and Crashed → CRITICAL, anything else → UNKNOWN. The previous severity is preserved across iterations so a WARNING pool can never downgrade a CRITICAL one. Status "2" (Repairing) is included in the WARNING set. README updated with the new mode. This is an alternative take on wernerfred#62 incorporating review feedback from issuecomment-4502847249.
- New --warning-free / --critical-free args: PERC_FREE thresholds (check_disk -w/-c convention). Precedence over upstream -w/-c. - Storage perfdata gets `;;;0;<storage_size>` (value;warn;crit;min;max) so Graphite-backed forecast plugins can compute 'days until full'. Backwards-compatible. _parse_pct accepts '10', '10%', ' 5 % '. Patch from Imatic IT; 6 threshold scenarios verified locally.
Previously emitted `status=7` only — opaque without consulting the MIB. Now emits `status=7 (RaidSyncing)` using a mapping derived from the comment block already documenting the codes. Suggested by Imatic IT (operator hit status=7 in production, had to look up the meaning manually).

Adds a
raidmode that monitors the status of every Synology storage pool via SNMP. Behaviour:Notes:
WARNINGpool can never lower the state below aCRITICALone observed earlier in the loop.Repairing(2)is included in the WARNING set (it's an intermediate operation, not a failure).This is an alternative implementation of #62 that addresses the issues raised in #62 (comment) (severity downgrade, missing status
2, README↔code mismatch, explicit Degrade/Crashed classification).
