Note

Low Risk
Installer UX and provisioning argument assembly only; no auth or credential handling changes beyond omitting optional --location.

Overview
Interactive registration no longer asks for a carbon zone — only the client name is prompted. Location comes from TRACEBLOC_CLIENT_LOCATION when set, otherwise silently from the machine timezone via _detect_location_zone; if detection finds nothing, client create runs without--location (optional CLI behavior per cli#137).

Invalid-zone errors are clearer:_report_create_failure takes a source flag (env vs auto) so hints either point at fixing TRACEBLOC_CLIENT_LOCATION or explain timezone auto-derivation and how to override.

Tests cover the no-prompt flows (#354) and rejected-zone messaging (Bugbot #356); scripts/manifest.sha256 is updated for provision.sh.
