Research pipeline now produces an index note with:
- Executive summary (2-3 paragraphs synthesized from sections)
- Clickable links to each section note (/notes/{id})
- Section notes have parent_id pointing to the index
Also improves outline resilience: lowered minimum sections from 3
to 2, retries once on failure before falling back to monolithic note.

Replaces the single monolithic research note with topic-driven section notes
plus an index note. Two new LLM calls: _generate_outline (JSON outline, 3-8
sections) and _synthesize_section (300-600 word focused note per section,
parallelised via asyncio.gather). Public signature of run_research_pipeline
unchanged; falls back to single-note synthesis on outline failure or if all
sections fail.
Also extracts _build_sources_block helper and adds full test suite.
