Remove debug logging from Docker collection code

Agent changes:
- Changed docker ps and docker images commands to run without sudo
- cm-agent user is already in docker group, so sudo is not needed
- Fixes "unable to change to root gid: Operation not permitted" error
- Systemd security restrictions were blocking sudo gid changes

This fixes Docker container and image collection on systems with
systemd security hardening enabled.

Updated to version 0.1.178

 ## Core Architecture Principles
 
-### Individual Metrics Philosophy
+### Structured Data Architecture (✅ IMPLEMENTED v0.1.131)
-- Agent collects individual metrics, dashboard composes widgets
+
-- Each metric collected, transmitted, and stored individually
+Complete migration from string-based metrics to structured JSON data. Eliminates all string parsing bugs and provides type-safe data access.
-- Agent calculates status for each metric using thresholds
+
-- Dashboard aggregates individual metric statuses for widget status
+**Previous (String Metrics):**
+
+- ❌ Agent sent individual metrics with string names like `disk_nvme0n1_temperature`
+- ❌ Dashboard parsed metric names with underscore counting and string splitting
+- ❌ Complex and error-prone metric filtering and extraction logic

+## Enhanced Storage Pool Visualization
+
+### Auto-Discovery Architecture
+
+The dashboard uses automatic storage discovery to eliminate manual configuration complexity while providing intelligent storage pool grouping.
+
+### Discovery Process
+
+**At Agent Startup:**
+
+1. Parse `/proc/mounts` to identify all mounted filesystems
+2. Detect MergerFS pools by analyzing `fuse.mergerfs` mount sources
+3. Identify member disks and potential parity relationships via heuristics
+4. Store discovered storage topology for continuous monitoring
+5. Generate pool-aware metrics with hierarchical relationships
+
+**Continuous Monitoring:**
+
+- Use stored discovery data for efficient metric collection
+- Monitor individual drives for SMART data, temperature, wear
+- Calculate pool-level health based on member drive status
+- Generate enhanced metrics for dashboard visualization
+
+### Supported Storage Types
+
+**Single Disks:**
+
+- ext4, xfs, btrfs mounted directly
+- Individual drive monitoring with SMART data
+- Traditional single-disk display for root, boot, etc.
+
+**MergerFS Pools:**
+
+- Auto-detect from `/proc/mounts` fuse.mergerfs entries
+- Parse source paths to identify member disks (e.g., "/mnt/disk1:/mnt/disk2")
+- Heuristic parity disk detection (sequential device names, "parity" in path)
+- Pool health calculation (healthy/degraded/critical)
+- Hierarchical tree display with data/parity disk grouping
+
+**Future Extensions Ready:**
+
+- RAID arrays via `/proc/mdstat` parsing
+- ZFS pools via `zpool status` integration
+- LVM logical volumes via `lvs` discovery
+
+### Configuration

+```toml
+[collectors.disk]
+enabled = true
+auto_discover = true  # Default: true
