Simplified keyboard controls by removing service restart functionality:
- Removed 'r' key restart functionality from Services panel
- Made 'R' key always trigger system rebuild regardless of focused panel
- Updated context shortcuts to show 'R: Rebuild Host' globally
- Removed all ServiceRestart enum variants and associated code:
- UiCommand::ServiceRestart
- CommandType::ServiceRestart

- Cleaned up pending transition logic to only handle Start/Stop commands
The 'R' key now consistently rebuilds the current host from any panel,
while 's' and 'S' continue to handle service start/stop in Services panel.
Resolved issues with transitional service icons not being properly visible:
- Removed 3-second timeout that was clearing pending transitions prematurely
- Fixed selection highlighting disappearing when transitional icons appeared
- Implemented conditional coloring for transitional icons:
- Blue when service is not selected

- Display "Agent Hash" in system panel under NixOS section
- Update metric filtering to include agent hash
This helps identify which version of the agent is actually running
when troubleshooting deployment or metric collection issues.
Update metric filtering to use exact metric names instead of prefix matching.
This resolves the issue where build version showed 'unknown' despite agent
correctly collecting the metric.
- Create NixOS collector for version and active users detection

Eliminate duplicate storage entries by removing old disk_count dependency.
Dashboard now uses pure auto-discovery of disk_{pool}_usage_percent metrics.
Fixes multiple storage instances (Storage 0, Storage 1, Storage root)
showing only proper tree structure format.
Add proper hierarchical tree display for storage pools and drives:
- Pool headers with status icons and type indication (Single/multi-drive)
- Individual drive lines with ├─ tree symbols and health status
- Usage summary with └─ end symbol and capacity status
- T: and W: prefixes for temperature and wear level metrics
- Themed status icons using StatusIcons::get_icon() with proper colors

Replace flat storage display with beautiful tree format:
● Storage steampool (multi-drive):
├─ ● sdb T:35°C W:12%
├─ ● sdc T:38°C W:8%
└─ ● 78.1% 1250.3GB/1600.0GB
Uses agent-calculated status from NixOS-configured thresholds.
Update CLAUDE.md with complete implementation specification.
Restructure storage display to handle new individual metrics architecture:
- Parse disk_{pool}_* metrics instead of indexed disk_{index}_* format
- Support individual drive metrics disk_{pool}_{drive}_health/temperature/wear
- Display tree structure: "Storage {pool} ({type}): drive details"
