TypeScript 7 does not load language service plugins. Building on the API sessions from #439, this adds GraphQL editor features through those sessions and an npm-packaged LSP proxy for clients that can launch a custom TypeScript server.

The native editor paths now provide diagnostics for unsaved documents, hover, resolved completions, schema definitions, cross-file fragment references and rename, quick fixes, and fragment extraction. VS Code connects to its existing native TypeScript server; other LSP clients can launch graphqlsp --stdio without a VSIX. Both paths require TypeScript 7.1+ and keep configuration in compilerOptions.plugins. An npm install and tsconfig entry alone do not activate GraphQLSP in stock VS Code with TS 7.

• Share language feature operations across the classic plugin and native sessions; preserve native LSP capabilities and ordinary TypeScript operations.
• Resolve GraphQL completion items locally, reject stale cross-file edits, and handle cancellation and native-mode transitions.
• Recover local schemas after edits, deletion, and recreation; await named schemas before the first request.
• Windows stays unsupported for TS 7: the sync client can't connect to API pipes there, and the relay is Unix-only.
• Add cross-platform packaging CI, a real VS Code harness, regression coverage, and setup/API/development documentation for both installation paths.

Validation

The runs below were on Windows, through a launcher-based relay that has since been removed (aa25882). They don't cover the supported macOS/Linux paths, which still need a run before merge.

Local validation on Windows with Node.js 22, VS Code 1.136.2, TypeScript Native Preview 1.0.1, and TypeScript 7.1.0-beta:

• 149 regression tests passed across 28 files; both packages typecheck.
• 13 automated checks passed against the installed final VSIX in an isolated real VS Code profile, including applied completion, rename, quick fixes, and extraction; schema recovery; server restart; and classic/native switching.
• The documented npm-only setup passed 7 checks in a separate project, including the exact standalone-check script, LSP launch command, hover, unsaved diagnostics, and shutdown.
• Independent adversarial review findings were addressed; its native shutdown stress run passed 14/14 cases. Documentation links were also checked through actual VSIX processing.

Limits

Native TS 7.1 can still hang in API-session cleanup. The proxy drains its worker, requests clean native shutdown, and uses a documented two-second fallback to terminate the native child and acknowledge shutdown before waiting for the client's exit.

macOS/Linux CI jobs are configured but have not been run locally. The newer middleware adapter has unit coverage; the actual editor run used the released extension's older API. Standalone .graphql language features and navigation from generated gql.tada turbo-cache result types back into queries remain outside this integration.
