The dynamic command tree is built from cached discovery data before
Cobra dispatches any command. A panic during that build (e.g. a
duplicate pflag registration fed by a poisoned cache, as seen before
1.0.32: "chat_permission_grant flag redefined: params") aborted every
invocation — including 'dws cache refresh', the very command that
repairs the cache. The only way out was manually deleting
~/.dws/cache/<partition>/tools/*.
Wrap the envelope-driven build in a local recover: on panic the CLI now
logs the failure, prints a stderr hint pointing at 'dws cache refresh',
and falls back to the hardcoded helper commands so utility commands
stay alive and users can self-heal.
