prefersReducedMotion: true does not stop spinner/indicator blinking

The prefersReducedMotion setting is set to true in both global (~/.claude/settings.json) and project-level (.claude/settings.json) settings, but the blinking ⏺ spinner animation still plays during thinking/tool execution.

Version: 2.1.84
Platform: macOS (Darwin 25.3.0)

Steps to reproduce:

1. Set "prefersReducedMotion": true in ~/.claude/settings.json
2. Start a Claude Code session
3. Observe the ⏺ indicator still blinks/flickers during tool use and thinking

Expected: Animations should be reduced or static when this setting is enabled.
Actual: The spinner continues to animate identically to when the setting is off.
