The @google/generative-ai SDK has been deprecated by Google. This switches
to the successor @google/genai package and rewrites the Gemini provider
against the new stateless models/chats API.
BREAKING CHANGE: GeminiConfig.safetySettings now uses the SafetySetting
type from @google/genai. Consumers passing this field must update their
import from '@google/generative-ai' to '@google/genai'. The shape of the
type is similar but not identical.
Notable simplifications enabled by the new SDK:
- No per-model client caching: generateContent specifies model per-call
- Single code path for both single- and multi-turn (full contents array
is passed to generateContent directly; no more startChat branching)
- Stream chunks expose .text as a property (was .text() method)
- Stream iteration is direct on the response (no .stream sub-property)
Default model bumped from gemini-1.5-flash to gemini-2.5-flash.
- Add typescript ^6.0.0 as devDependency for verified builds
- Widen peerDependency to ^5 || ^6 to keep TS 5 consumers supported
- tsconfig.build.json: set explicit rootDir (required by TS 6 when outDir is set)
- tsconfig.build.json: replace deprecated moduleResolution "node" with "bundler"
Also refreshes bun.lock to pick up @anthropic-ai/sdk 0.65.0 and
@types/node 24.12.4 within existing version ranges. All bumps stay
within the same major to avoid breaking changes.
