macOS: Plugin requires Claude Code restart to take effect after setup

[xiaodream551-a11y]

Description

After running /claude-hud:setup, the statusLine config is written to ~/.claude/settings.json successfully, but the HUD does not appear until Claude Code is fully restarted.

The setup skill (Step 3) implies the HUD should work immediately after the config is applied — there is no mention of needing to restart Claude Code. However, on macOS, a restart is required for the statusLine to take effect.

Steps to Reproduce

1. Run /claude-hud:setup in an active Claude Code session
2. Complete all setup steps — config is written to ~/.claude/settings.json
3. Observe that the HUD does not appear in the current session
4. Restart Claude Code
5. HUD now appears correctly

Expected Behavior

The HUD should appear immediately after setup without requiring a restart, or the setup instructions should mention that a restart is needed.

Environment

• Platform: macOS (Darwin, Apple Silicon M4)
• Shell: zsh
• Runtime: bun
