v5.0.4

Added

• design skill references/ folder: Design phase now populates <spec_dir>/references/ with external method/API reference documents (name, purpose, required parameters), reducing hallucinated external code during implementation.
• apltk codegraph as dedicated workflow step: spec and docs-project skills now run apltk codegraph survey before reading requirements, ensuring BDD boundaries align with real code. design uses codegraph survey before architecture design.
• Brownfield refactoring assessment: design skill now includes explicit T1–T3 refactoring planning for brownfield changes as a standard workflow step.
• Worker prompt separation: plan and qa skills now store worker prompts in plan/*.md and fix/*.md files respectively, keeping coordinator prompts focused on strategy. PROMPT.md/FIX.md Reference sections cite all worker prompt paths and code file paths.
• Prompt generation guidance consolidated: Notes on writing quality worker prompts moved from PROMPT.md/FIX.md templates into plan/qa SKILL.md, aligning with the optimise-skill principle of behavioral guidance in SKILL.md.

Changed

• Self-review renamed to Verification: design and spec skills now use "Pre-delivery Verification" with explicit completeness and quality checks, plus code traceability validation.
