hybrid-dev

Hybrid Dev Workflow Skill initial release:

- Introduces a clear three-phase hybrid workflow combining local model planning, Copilot implementation, and local model validation.
- Defines product output directories for each development phase (A, B, C).
- Specifies step-by-step workflow triggers, handoff points, and prompt usage for each phase.
- Establishes phase gate rules to enforce quality: require quantitative acceptance criteria, test coverage, and defect closure before progressing.
- Recommends a minimum iterative pace with deliverables: requirement changes, implementation notes, and test results per cycle.
