ShadowMountPlus 1.7alpha2

• Improved runtime path and title validation.
• Fixed game mount lifecycle, restart, suspend, and shutdown handling.
• Deferred runtime teardown until ShellCore completes unmountWorkspace.
• Made nullfs and image unmounting safer by avoiding forced teardown and reporting mount dependencies when a device is busy.
• Made the KStuff automount handoff and .kstuff_noautomount marker shutdown-safe.
• Added a public socket API at /system_tmp/shadowmount-api.sock.
• Added API documentation and a test payload (api-test.elf) for third-party developers.
