Adds examples/patterns/meeting-summarizer.ts — fan-out pattern
tailored for meeting transcripts. Three specialists run in parallel
on the same transcript:
- summary: three-paragraph prose summary
- action-items: Zod-validated { task, owner, due_date? }[] schema
- sentiment: Zod-validated per-participant tone + evidence
Each specialist's wall duration is recorded, and the script asserts
parallel wall time < 70% of the sum of per-agent durations to prove
fan-out gives a real speedup. An aggregator then merges the three
outputs into a single Markdown report with four H2 sections
(Summary, Action Items, Sentiment, Next Steps).
Ships with examples/fixtures/meeting-transcript.txt — a 350-word
engineering standup transcript designed so the three schemas exercise
cleanly (concrete owners + due dates for action items, a mixed-tone
on-call engineer for sentiment).
Lint and test pass on upstream/main.
