Restore complete MergerFS and SnapRAID functionality to disk collector

Updated the disk collector to include all missing functionality from the
previous string-based implementation while working with the new structured
JSON data architecture:

- MergerFS pool discovery from /proc/mounts parsing
- SnapRAID parity drive detection via mount path heuristics
- Drive categorization (data vs parity) based on path analysis
- Numeric mergerfs reference resolution (1:2 -> /mnt/disk paths)
- Pool health calculation based on member drive SMART status
- Complete SMART data integration for temperatures and wear levels
- Proper exclusion of pool member drives from physical drive grouping

The implementation replicates the exact logic from the old code while
adapting to structured AgentData output format. All mergerfs and snapraid
monitoring capabilities are fully restored.
