gsxdsm 2bb8537352 FN-8616: make agent tool-output limits configurable

Expose the shared agent tool-output budget as a scoped operator setting with an explicit no-limit option.

- Resolve global and project output caps with a safe finite default and zero sentinel.
- Propagate configured budgets through PI and plugin runtime tool wrappers.
- Add settings controls, localized labels, documentation, and regression coverage.
