## Summary
Allow projects using TypeScript 7 to enable `emitDecoratorMetadata()`
without adding the TypeScript 6 compiler to every Trigger.dev CLI
installation. Addresses #4500.
## Fix
The extension now resolves TypeScript from the project and
feature-detects the legacy compiler API. TypeScript 5 and 6 continue
using the project's compiler, while TypeScript 7 projects can install
Microsoft's optional `@typescript/typescript6` compatibility package
alongside TypeScript 7.
When no compatible compiler API is available, the build reports an
actionable installation error. The extension documentation includes
setup commands for npm, pnpm, and Bun.
Verified with TypeScript 5, TypeScript 6, TypeScript 7 with and without
the compatibility package, emitted decorator metadata, packed ESM and
CommonJS consumers, package export checks, and typechecking.
