CLI overview

Entry point: bin/carina.ts dispatches to src/cli/registry.ts (44 commands).

carina                  # interactive chat (CLI gateway)
carina help             # grouped command list
carina doctor           # health checks
carina completion bash  # shell completion

Config lives in ~/.carina/:

File	Purpose
.env	API keys and secrets
config.yaml	Provider, model, Scout URL
toolsets.yaml	Per-platform tool toggles
credentials.json	API key pools and OAuth tokens

Wizard: carina setup writes initial .env.
