Orbit Dictation is now Comet, plus a refreshed Orion icon

What shipped

• •macOS dictation app renamed: Orbit Dictation → Comet. The .app, the DMG, the GitHub release titles, the menu-bar entry, and the website landing page (now /comet) all carry the new name. Existing installs keep updating cleanly because the bundle identifier, Sparkle update chain, and Keychain account are unchanged.
• •/orbit-dictation permanently redirects to /comet so every previous link still resolves.
• •New Comet app icon — handheld microphone silhouette with the Orbit planet as the head. Visually pairs with Orion as siblings in the Orbit family.
• •New Orion app icon — Orbit planet with three AI-style sparkles around it. Replaces the planet-only mark and reads more clearly as 'AI dock assistant' at glance.
• •Comet stays menu-bar-only at all times — no Dock icon flips when Settings or About windows open.
• •Orion's release notes now describe him as 'Orbit's assistant for your macOS dock' rather than 'the founder of Orbit.' Long-running framing fix; matches the system prompt's positioning.
