Kicks off v3-alpha on branch v3-dev. Locked decisions: rate-limit % via CLI
subscriptions, provider switch on both PC and watch, brand-colored themes
(clay / OpenAI green / z.ai blue). Architecture: daemon Provider abstraction,
`pv` payload field, firmware runtime palette + shared LVGL styles for live
recolor. Milestones M1 (framework+Anthropic+theming) → M2 (OpenAI) → M3 (z.ai).
