TypeScript 7 is a native rewrite that no longer ships lib/typescript.js, which Next.js and ts-morph still require for programmatic API access. - Add typescript-7 (7.0.2) for the native tsc compiler via typecheck script - Keep typescript (^6.0.2) for Next.js build type-checking and ts-morph - Set explicit types: ["node"] in tsconfig for TS7 default behavior - Add typecheck script and CI job using the TS7 compiler - Remove stale pnpm-lock.yaml (project uses bun.lock) Co-authored-by: Bartosz Zagrodzki <Bartek532@users.noreply.github.com>

TypeScript 7 cannot replace the main typescript package yet because Next.js requires lib/typescript.js for build-time type checking. - Pin typescript-7 to 7.0.2 for the native TS7 compiler - Keep typescript@^6.0.2 for Next.js and ts-morph API access Co-authored-by: Bartosz Zagrodzki <Bartek532@users.noreply.github.com>
TypeScript 7 cannot be the sole dependency yet because Next.js requires lib/typescript.js during build. The typescript-7 alias was unused after dropping the typecheck script. Co-authored-by: Bartosz Zagrodzki <Bartek532@users.noreply.github.com>
- Set typescript to 7.0.2 (native compiler) - Add @typescript/native-preview for Next.js compatibility - Enable typescript.ignoreBuildErrors until Next.js supports TS7 API Co-authored-by: Bartosz Zagrodzki <Bartek532@users.noreply.github.com>
