dsh-specify-lite: A DSH Native Driver Development Workflow Plugin

`dsh-specify-lite` is a lightweight, plugin-based DSH development tool designed to simplify Spec-Driven Development (SDD) workflows in local model environments. It is independent of GitHub Spec-Kit and does not require Git changes or subagent orchestration, managing development steps through a three-part model of specifications, plans, and tasks. Users can initialize a project following the workflow, define the constitution and specifications, generate plans and task lists, and then perform implementation and validation. The tool supports Git immutability and single-model operation, making it suitable for project development that requires standardization and low complexity.
