Module assembly 

Context assembly — orchestrates rendering, budget allocation, ordering, and sections.

ContextAssembler takes &[SearchHit] + FormatPolicy and produces a FormattedContext ready for LLM consumption.

RF-4: Structured Context Rendering

Three intent-aware rendering modes improve how grains are presented:

1. Aggregation mode — entity summary header + grouped-by-entity rendering when entity_count is present in the RecallResult.
2. Timeline mode — chronological rendering with date prefixes when temporal intent is detected (temporal_expr, time range, or multi-day span).
3. Relevance highlighting — top-5 “Most Relevant” section + “Additional Context” when result set exceeds 10 grains.

Modes are mutually exclusive, checked in priority order (aggregation > timeline > relevance). JSON output bypasses all modes.
