v0.2.0 — reference scholar + synthesis_doc_builder

What's new in v0.2.0

This release ships the deferred reference implementation that the v0.1.0 protocol bundle pointed at. v0.1.x consumers see no breaking changes — the SKILL protocol surface is unchanged. The new lib/ code is pluggable reference for orchestrators wiring deep_research into their own runtime.

Added

• lib/scholar.py — stdlib-urllib adapter over OpenAlex, Semantic Scholar, PubMed, arXiv, Europe PMC, Crossref, Unpaywall. Actions: search, multi_search, get, find_doi, resolve_oa. Uniform normalized-hit schema across sources.
• lib/synthesis_doc_builder.py — python-docx + matplotlib helper that renders the synthesis doc (forest plot, PRISMA flow, stance heat-table) with a pluggable upload callback.
• pyproject.toml — installable package. Core stdlib-only; [viz] extra adds python-docx, matplotlib, numpy.
• tests/test_scholar_smoke.py, tests/test_synthesis_doc_builder_smoke.py — stdlib unittest, network-free, soft-dep-aware skips.

Changed

• lib/scholar.py exposes configure(contact_email, app_name) and honors SCHOLAR_CONTACT_EMAIL env. Without it, polite-pool mailto= is omitted and a generic UA is sent. Embedding dedup pluggable via set_embedding_deduper(fn).
• lib/synthesis_doc_builder.py decouples upload via Uploader = Callable[[Path, str, str], dict]. No uploader → returns local .docx path, uploaded=False.
• manifests/deep-research.v0.4.json bumps tool.version to 0.2.0.
• SKILL.md drops the v0.1 hedge.
• README.md updated for v0.2.0; quickstart shows pip install "deep-research[viz]".
