cfgloader now searches only %ProgramData%\mototrbo on Windows since the SCM working dir and LocalSystem profile are useless. mototrbod's data_dir defaults to %ProgramData%\mototrbo\data on Windows. Adds a WiX v4 MSI (installer/windows/mototrbod.wxs) that installs to C:\Program Files\mototrbo, drops a default mototrbod.toml plus data and logs dirs under C:\ProgramData\mototrbo, and registers mototrbod as a LocalSystem auto-start service. The service install/uninstall cobra subcommands are removed in favor of the MSI as the single source of truth; start/stop/run remain. Adds .github/workflows/release.yml to build the MSI on every v* tag and publish it as a GitHub release asset. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
