test(inputs): add test for read but unmatched file with inference off

branchseer · claude · branchseer · commit aec09f3fd76c · 2026-01-14T11:57:47.000+08:00
- Update print-file to accept multiple files
- Add positive-globs-reads-unmatched task that reads both src/main.ts
  and src/utils.ts but only has src/main.ts in its inputs glob
- Verify that modifying utils.ts (read but not matched) results in
  cache hit when inference is disabled
