fix(uninstall): MANDATORY tar backup in ALL modes (safe/settings-only/full)

Browse Source 
Per user demand after data loss incident: never trust mode flags alone.
Previously only `full` mode created tar.gz backup. Now `safe` and
`settings-only` also create full tar.gz of ~/.claude (resp .codex,
.gemini, .qwen) BEFORE any mutation. If backup fails, refuse to
proceed for that user — skip to next.

Restore is always one command:
  tar -xzf ~/.<tool>.uninstall-backup.<TS>.tar.gz -C ~

Applies to all 4 scripts: uclaude, ucodex, ugemini, uqwen.
