Autoupdate fix status

Initial failure: npm install failed with ERESOLVE — the npm-check-updates baseline bumped typescript to ^7.0.2, but typescript-eslint@8.64.0's peer dependency requires typescript >=4.8.4 <6.1.0. TypeScript 7.x is too new for the current typescript-eslint release, so the dependency tree was unresolvable.

Fix: Pinned typescript to ^6.0.3 (latest 6.x release, satisfies typescript-eslint's peer range) in package.json, then regenerated package-lock.json via npm install --no-audit --no-fund. No product logic was touched — this is a pure devDependency compatibility pin.

Verification (all exit 0 on this branch):

• npm install --no-audit --no-fund — exit 0
• npm run build (prebuild eslint + tsc types/cjs/esm + package shim) — exit 0
• npm test (tsx --test test/library.test.ts, using the IRECEIPTPRO_API_KEY secret) — exit 0, 4 passed / 0 failed

Pushed: commit e4a58a4 — "fix(deps): pin typescript to ^6.0.3 for typescript-eslint compatibility"
