The single auto-refreshing zero-JS status page gave operators a 25-column
wall and no way to drill into one connection. This adds a Bootstrap fleet
dashboard (filterable/sortable KPI table) and a per-PLC detail page with a
real-time debug view of raw PLC-side BCD vs. decoded client-side values,
streamed live over a SignalR feed. The debug view is fed by an on-demand
per-tag value capture, armed only while a detail page is open. All assets
(Bootstrap, SignalR client, fonts) are embedded so the UI works unchanged
on firewalled networks; GET /status.json is untouched for scrapers.

Make the service build, run, and install on Linux as a first-class
target while keeping the Windows Service + Event Log behaviour intact.
- Build: drop the hardcoded win-x64 RID — single-file publish now works
for any RID. publish.ps1 gains -Rid; new publish.sh for Linux hosts.
- Diagnostics: DiagnosticSinkSelector picks the Error+ sink per host —
Windows Event Log under the SCM, local syslog under systemd
(Serilog.Sinks.SyslogMessages), none for interactive runs. The
EventLog truncation helper is extracted so it is testable cross-OS.
- Host: Program.cs registers AddSystemd() alongside AddWindowsService().
- Config: a RID-conditioned appsettings template ships Windows or Unix
paths; both templates are schema-validated by a test.
- Install: systemd unit (Type=exec) plus install.sh / uninstall.sh.
Also fixes two cross-platform bugs found while testing: install.ps1
and uninstall.ps1 used New-EventLog / Remove-EventLog (absent in
PowerShell 7), and the E2E sim launcher hardcoded Windows venv paths.
- Docs updated across README, CLAUDE.md, and docs/ for dual-platform.
413 tests pass on Windows; 374 (all non-simulator) on Linux.
