cortex/providers — New provider architecture (v1.2.1+).

Replaces cortex/llm/ provider stack with a clean three-mode system:
  host     — piggyback on OpenClaw host credentials
  byok     — user-supplied API keys
  bundled  — ElectricSheep managed keys (future)

See: docs/architecture/provider-architecture-v121.md
