feat(ai): ImagesModels collections mirroring the chat-side design

Browse Source 
createImagesModels()/ImagesProvider/createImagesProvider() give image
generation the same shape as chat: sync model reads, explicit async
refresh(provider?) with in-flight dedupe, provider-resolved auth, and
never-rejecting generateImages() (failures return AssistantImages with
stopReason error). Auth resolution is shared with the chat side via the
free-standing resolveProviderAuth() in auth/resolve.ts, which also owns
ModelsError; both collections pass their store/context as arguments.

The OpenRouter implementation moves to api/openrouter-images.ts with a
lazy wrapper; openrouterImagesProvider() factory plus
builtinImagesProviders()/builtinImagesModels() land in providers/all.
The ImagesProvider id type alias is renamed to ImagesProviderId
(mirror of Provider -> ProviderId). The old global image API
(getImageModel*, generateImages, registerImagesApiProvider) stays on
/compat, its registration shim repointed at the moved implementation.

README: Quick Start uses builtinModels(), the full streaming event
switch, image generation and the development checklist are restored in
full, image generation documents the new collections with compat noted
for the old API, plus the review fixes (builtinModels options,
credential-store mention for browsers, ImagesModels notes).

- One provider factory per built-in provider under `@earendil-works/pi-ai/providers/*` (e.g. `anthropicProvider()`, `openrouterProvider()`), plus `@earendil-works/pi-ai/providers/all` with `builtinProviders()`/`builtinModels()` and typed `getBuiltin*` catalog reads. Generated catalogs are split per provider, so importing one provider pulls one catalog; `sideEffects` metadata makes the package tree-shakeable.
- OAuth flows (Anthropic, OpenAI Codex, GitHub Copilot) gained `OAuthAuth` adapters (`login`/`refresh`/`toAuth`) on unified `prompt()`/`notify()` login callbacks; Copilot's per-credential base URL is derived in `toAuth()`.
- `fauxProvider()` returns a faux `Provider` for tests built on explicit `Models` collections.
- Image generation mirrors the chat-side design: `createImagesModels()`/`ImagesProvider`/`createImagesProvider()` with sync model reads, explicit `refresh()`, provider-resolved auth, and never-rejecting `generateImages()`; `openrouterImagesProvider()` factory plus `builtinImagesProviders()`/`builtinImagesModels()` in `providers/all`. The `ImagesProvider` id type alias is renamed to `ImagesProviderId`; the old global image API stays on `/compat`.
- When Amazon Bedrock rejects an unsupported data retention mode, the error now links the AWS data retention documentation ([#5561](https://github.com/earendil-works/pi/pull/5561) by [@unexge](https://github.com/unexge)).
