[Phase 2.1] Synthesis workflow definition (#12)

## Changes - `workflow/synthesis.go` — 5-stage synthesis pipeline as Temporal workflow - `workflow/synthesis_test.go` — 5 tests using Temporal test framework ## Pipeline Stages 1. **ChunkAndEmbed** — chunk text + generate embeddings 2. **ExtractEntities** — LLM entity extraction with reflection 3. **ExtractFacts** — pattern + LLM fact extraction 4. **DetectContradictions** — pre-filter + LLM verification 5. **PersistSynthesis** — save all results to DB
