Greptile Summary

Adds pull-based LSP diagnostics and replaces the legacy TypeScript language server with native TypeScript 7.

• Schedules diagnostic pulls after the editor’s LSP extensions initialize and when documents change or servers request a refresh.
• Handles additional server-to-client requests, including workspace configuration and workspace-folder queries.
• Propagates workspace configuration and launcher log-filtering options through server registration.
• Updates the JavaScript/TypeScript server definition to install and launch native TypeScript 7.

Confidence Score: 5/5

The PR appears safe to merge.

No blocking failure remains.
