dsh-toolkit: Collection Install Entry for Ten Zero-Dependency Deterministic Tools

The omdsh-dev/dsh-toolkit bundles ten deterministic tools—time, encoding, json, calculator, csv, regex, markdown, diff, stat, and schema—as vendored snapshots into a single collection, offering unified testing across 723 use cases and batch installation scripts. It supports installing independent bundles as subpackages to web or headless profiles, or selecting a meta package for a single atomic mount. Licensed under MIT, version 0.0.1, it is designed for developers who need basic data processing within a DSH agent and require reproducible configurations.
