redesign: Concrete Brutalism — warm concrete palette, Inconsolata + Instrument Sans

Kill the AI slop. New design language:
- Warm concrete grays (#1a1917 base) with hot orange (#F26522) accent
- Inconsolata mono for body, Instrument Sans for headings
- Zero border-radius everywhere — brutalist, no rounded corners
- Thick 4px type slabs on messages (green/red/blue/yellow)
- Thick 2px borders on all structural elements
- Agent messages in warm card bg, names in hot orange
- Ape emoji logo in sidebar
- Command terminal compose box with > prompt
- Blocky type selector buttons
