Automation permission not triggered when installed via brew tap

Description

When ClaudeNotifier is installed via brew tap, the setup command does not trigger the macOS automation permission window for iTerm2.

Expected Behavior

Running claude-notifier setup should prompt the user for Automation permission to control iTerm2 (needed for the focus-on-click feature).

Actual Behavior

The automation permission dialog is not shown when installed via brew tap.

Steps to Reproduce

1. Install via brew tap: brew install zraqs/tap/claude-notifier
2. Run claude-notifier setup
3. Observe that no automation permission dialog appears

Environment

• Installation method: Homebrew tap
• macOS version: [to be filled]
