refactor: remove dead exported types from picker.ts and spawn-config.ts (#2553)

PickOption, PickConfig, and PickResult interfaces in picker.ts were exported
but never imported by any external module. SpawnConfig type in spawn-config.ts
was similarly exported but not used outside the module. Made all four private
to reduce the public API surface.

Bump CLI patch version to 0.17.2.
