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.
