hayro-postscript 0.1.0 is the token scanner hayro-cmap uses for the CMap streams PDFs embed. Its object reader skipped each `<<` or `>>` by calling itself again, so a stream holding a long run of `<` or `>` bytes recursed once per pair and aborted the process with a stack overflow. Vendor the crates.io package unchanged and patch `object::read` to skip those runs in a loop, returning the same next object as before. Wire it in like the other Hayro crates: workspace exclude, [patch.crates-io] entry, SOURCE.json with registry and local hashes, the backend test script, NOTICE, ATTRIBUTION.md and the reader README. Tests cover a million `<` and a million `>` bytes, `<< /A 1 >>` and nested `<<<< /X >>>>` runs.
