Development Plan and Execution Prompts

Convert source documents into a plan that remains valid as milestones merge:

• .docs/DEVELOPMENT_PLAN.md — the committed, authoritative milestone plan.
• .docs/EXECUTION_PROMPTS.md — the committed, authoritative /goal contract for each milestone.
• .docs/DEVELOPMENT_PLAN_HISTORY.md — the single local, append-only design-evidence ledger. It must be gitignored.

This skill plans from documents only. Do not implement product code, create branches, open PRs, or execute the generated prompts.
