/**
 * `@pubscript/ai` — the AI provider layer for PubScript.
 *
 * A self-contained, SSE-based provider abstraction that talks to any
 * OpenAI-compatible endpoint with streaming, thinking/reasoning params, and
 * the token-budget engine from `packages/core`. See CHUNK#8.md.
 *
 * Public API:
 * - `streamCompletion`, `collectStream`, `complete` — the completion client.
 * - `measureBudget`, `enforceBudget` — budget helpers.
 * - `discoverLocalProviders` — local provider discovery.
 * - `getProvider` — resolve a provider config into an adapter.
 * - `normalizeThinking` — thinking-param mapping.
 * - Re-exports of the token budget engine from `packages/core`.
 * - All types and error classes.
