docs(impact): add IMPACT.md adoption and engagement log (closes #3) (#8)

Creates IMPACT.md at repo root as a living, honest record of adoption
signals, citations, talks, and engagement roadmap. No fabricated
testimonials or organizations — empty tables use "TBD — populated
quarterly" placeholders. Seeded with confirmed GitHub stats (11 stars,
8 forks, 2 watchers) as of 2026-06-01.

Also adds a single Impact link line to README.md just below the badges,
pointing readers to IMPACT.md. No substantive README content changed.

+## Case Studies
+
+The framework's reference case studies, with the audience each targets:
+
+- **[SMM Starter](docs/case_studies/smm_starter.md)** —
+  Laptop-only deployment with Ollama for small-to-mid manufacturers with
+  no existing data platform. Targets NIST MEP center client base.
+- **[CHIPS-Era Tier-2/Tier-3 Supplier](docs/case_studies/chips_supplier.md)** —
+  AWS Bedrock / GovCloud deployment for defense-adjacent and
+  semiconductor-ecosystem suppliers needing CMMC L2 alignment.
+
+Additional case studies will be added as the framework is deployed in
+production environments.
+
+## Engagement Roadmap
+
+The following outreach is planned to drive adoption with the U.S.
+manufacturing community:
+
+- [ ] arXiv whitepaper submission (Q3 2026 target)
+- [ ] Outreach to 3 NIST MEP regional centers, starting with the Texas
+      Manufacturing Assistance Center
+- [ ] Outreach to CESMII, MxD, and ARM Institute (Manufacturing USA)
+- [ ] Conference submission: IIoT World, Hannover Messe USA, ARC Industry
+      Forum
+- [ ] Academic outreach: 2-3 university Industry-4.0 labs publishing in
+      agentic AI for manufacturing
+
+## How to Cite
+
+If you use this framework in research, see the `@software` block in
+[`CITATION.cff`](./CITATION.cff) and the citation snippet in the [README](./README.md#citation).
+
+## How to Report Use
+
+Using this framework in production, research, or teaching? Open a PR
+adding a row to the relevant table above, or open an issue with the
+"impact" label and we'll add it. Citations and adoption are valuable
+signals for the framework's continued development and for the U.S.
+manufacturing community generally.
