update
Update the installed xtraq global tool to the latest available version. Installs the latest published xtraq global tool package on the current machine. When invoked from CI this command can keep runner environments current before a build.
Configuration & Environment Bootstrap
The xtraq CLI keeps project settings deterministic by committing a `.xtraqconfig` file and limiting the local `.env` to secrets plus logging toggles. CLI flags can still override behaviour when required, while process-level environment variables are now restricted to connection strings and diagnostic switches so the tracked JSON snapshot remains authoritative.
