v0.8.0

• New workflows functional-refactoring and readable-code (code area), both
  behavior-preserving and analyze-and-fix. functional-refactoring makes a
  module's hidden inputs explicit at the edge, extracts its decisions as pure
  functions tested without stubs and layers its functions (ideas from Grokking
  Simplicity, concept only). readable-code resolves reading obstacles inside
  working code (names, nesting, comments, error flow) through the code-shape
  vocabulary (ideas from Clean Code, concept only).
• ROUTING.md routes refactoring requests by symptom; a vague request with both
  symptoms runs functional-refactoring first and readable-code as a later
  slice. abstraction-layers, module-design, code-consolidation and
  house-patterns name the new boundaries.
• Evaluation cases E63 to E66 (66 total).
