A visual polish pass on the v0.8 GUI.
- New logo — a minimal 'glass box' mark (a transparent cube with a node), tying the identity directly to the glass-box concept. It now appears in the app (sidebar, message avatars, favicon), the README, and the animated hero.
- Removed all emoji and decorative glyphs from the app UI, README, and docs for a cleaner, more professional look — buttons use plain text or minimal line icons, and the empty-state copy is less generic.
No API changes. Fresh binaries attached.
