macOS 15 (Sequoia) and macOS 26 (Tahoe) introduced security restrictions that prevent third-party input methods from being enabled programmatically using TISEnableInputSource(). This commit addresses the issue by: 1. Detecting when automatic activation fails on macOS 15+ 2. Showing a user-friendly dialog with step-by-step instructions 3. Offering to open System Settings directly to the Input Sources page 4. Updating README with installation instructions for macOS 15+ 5. Adding FAQ entry explaining the manual activation requirement The activate script now checks if the input method was successfully enabled after calling TISEnableInputSource(). If it fails on macOS 15 or later, it displays a dialog guiding users to manually enable the input method through System Settings. Fixes automatic activation issue on macOS Sequoia and Tahoe.
