_build_style_context rewritten from 10-line summary to comprehensive
style guide including:
- Tone rules per appeal type (warm for licensing, cold for levy)
- 15 mandatory expressions ("כידוע", "ברי כי", "אין בידנו לקבל")
- Discussion structure rules (continuous prose, conclusion first)
- Per-party phrasing templates (appellants, committee, permit applicants)
- DB patterns grouped by type (phrases, transitions, openings, closings)
This addresses the main quality gap: style rated 2/5 because the output
was "dry and overly formal" vs Dafna's "direct and clear" voice.
