Autoupdate check status: fixed and green

Initial failure: npm install failed with ERESOLVE — the autoupdate baseline bumped typescript to ^7.0.2, but typescript-eslint@8.64.0 (the latest published version) still peer-depends on typescript >=4.8.4 <6.1.0. No release of typescript-eslint supports TypeScript 7 yet, so lint/build/test:ts couldn't even install.

Fix: Pinned typescript back to ^6.0.3 (the newest 6.x release, still within typescript-eslint's supported peer range) in package.json, and regenerated package-lock.json accordingly. No product logic (src/) touched.

Verification (all exit 0 after the fix):

• npm install --no-audit --no-fund ✅
• npm run lint ✅
• npm run build ✅
• npm run test:ts ✅ (5/5 tests pass)

Pushed commit: 9b1af1e — fix(deps): pin typescript to <6.1.0 for typescript-eslint compatibility
