Feature request: disable/replace whimsical status-spinner text with professional alternatives

The status spinner shown during processing/tool execution currently cycles through whimsical, non-literal words (e.g. "Percolating…", "Noodling…"). While playful, this doesn't fit professional/enterprise use — especially during serious, client-facing, or compliance-sensitive work.

Request:

• Add a setting (e.g. in settings.json, or an env var) to disable the whimsical word rotation
• When disabled, show plain/literal status text instead — e.g. "Thinking…", "Processing…", "Reading…" — reflecting the actual operation underway, rather than random filler words
• Optionally allow users to pick from a small set of professional alternatives as a style preference

Currently there is no documented way to configure or disable this (confirmed via Claude Code docs — no relevant settings.json key, env var, or CLI flag exists).
