fix(ai): remove legacy raw API subpaths

packages/ai/CHANGELOG.md

@@ -6,7 +6,7 @@
 
 - The root entrypoint (`@earendil-works/pi-ai`) is now core-only and side-effect free. The old global API moved to the temporary `@earendil-works/pi-ai/compat` entrypoint, a strict superset of the root: switching a file's import path is the only migration step. Moved symbols include `stream`/`complete`/`streamSimple`/`completeSimple`, `getModel`/`getModels`/`getProviders` (now deprecated aliases of `getBuiltinModel`/`getBuiltinModels`/`getBuiltinProviders` from `@earendil-works/pi-ai/providers/all`), `registerApiProvider`/`unregisterApiProviders`/`resetApiProviders`/`getApiProvider`, `getEnvApiKey`/`findEnvKeys`, `setBedrockProviderModule`, the per-API lazy stream wrappers (`anthropicMessagesApi`, ...), and the image-generation API.
 - Renamed the `Provider` type to `ProviderId`. `Provider` now names the runtime provider interface (id, name, auth, model listing, stream behavior).
-- API implementation modules moved from `src/providers/` to `@earendil-works/pi-ai/api/*`, renamed by API id (`anthropic` -> `api/anthropic-messages`, `google` -> `api/google-generative-ai`, `mistral` -> `api/mistral-conversations`, `amazon-bedrock` -> `api/bedrock-converse-stream`), each exporting exactly `stream` and `streamSimple`. The old per-impl export names (`streamAnthropic`, `streamSimpleAnthropic`, ...) are gone; the legacy package subpaths (`./anthropic`, `./google`, ...) keep working and point at the new modules.
