Tests: bun run check

The commit message states "bump the internal Baton version to 0.2.8" and the VERSION file was updated accordingly, but the "version" field in package.json (line 3) remains at "0.2.0". The baton version CLI command reads from packageJson.version, so users running baton version will still see 0.2.0. If the intent is to bump the version that users see, the package.json version should also be updated to 0.2.8.

ccr:label=wrong — AGENTS.md:50-51 明确规定根 VERSION 是项目内部版本，npm package version 独立且不随其更新；本次只按逻辑改动递增内部 VERSION，不是 npm 发版。#cross-file
