fix(build): support decorator metadata with TypeScript 7

[carderne]

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.
