[Feature Request] Customizable spinner words via configuration

Bug Description
Feature request: user-customizable spinner / thinking words The spinner shows hardcoded gerunds ("Spelunking…", "Pondering…", etc.). Please expose them as a configuration surface — e.g. a spinnerWords array in settings.json, or a path to a user-supplied word file. Use case: matching the spinner's tone to a configured assistant persona (and, more generally, team/brand voice). They currently live in the shipped bundle, so the only workaround is editing installed source, which every update wipes out.
