AIManager v0.1.1

• Fixed the macOS "damaged and can't be opened" error. v0.1.0 shipped with no code signature at all, which Apple silicon Gatekeeper rejects with an unbypassable "damaged" dialog. Builds are now ad-hoc signed: the first open shows a "cannot verify" prompt instead — click Done, then System Settings → Privacy & Security → Open Anyway (macOS 14 and earlier: right-click → Open). If you already have a v0.1.0 copy, run xattr -cr /Applications/AIManager.app or just install this version over it.
• New app icon. A clean letter-A tile with crisp edges and transparent corners.
