- 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.
