version.ts

// The version this server reports in `serverInfo`, read from package.json so
// it cannot drift from the published version (#4472). The TypeScript servers
// are versioned by changesets, whose "Version Packages" PR edits only
// package.json and CHANGELOG.md: a version literal in the source would stay
// behind at the first bump. Same module as `memory` and `sequentialthinking`.
