docs: further optimize style guide as delta-only document
- Add opener declaring adherence to Google Style Guide and Diataxis
- Remove generic Google style guide sections (Visual Hierarchy patterns,
Tables constraints, Code Blocks, Lists, Assets)
- Remove Diataxis explainer content (Document Types table, "X documents
do Y" explanatory sentences, Before/After example)
- Keep all project-specific structure templates and checklists
- Consolidate rules into single Project-Specific Rules table
Result: 367 lines (down from 597), pure delta document assuming
LLM training knowledge of baseline standards.
