[FEATURE] Feature request: setting to hide animated "thinking" status words (Enchanting / Ideating / Spinning…)

Problem Statement

Summary

The VSCode Claude Code extension shows whimsical animated status labels while the model is thinking — "Enchanting…", "Spinning…", "Ideating…", "Cogitating…", etc. I'd like a setting to suppress these and show just a static spinner or a plain "Thinking…".

Why

They're fun for a while but become visually distracting during long sessions, especially when streaming a lot of small tool calls. A static label is less attention-grabbing when I'm reading code in an adjacent editor pane.

Proposed Solution

Suggested design

Add a setting to settings.json (and the VSCode extension settings UI), e.g.:

{
  "claudeCode.hideThinkingStatus": true
}
