docs(definitions): install the paper's Appendix B glossary as the canonical definitions

merge-output/DEFINITIONS.md holds the research paper's (v5 FINAL, February 2026)
Appendix B verbatim: eleven scenario definitions and six violence categories,
plus a mapping from DB labels to glossary names and the owner's clarifications
on the Detention flag from 2026-09-06/07. The README's own paraphrase is
replaced by a pointer so there is one source of truth.

+### Definitions (read before classifying anything)
+The canonical definitions of the eleven scenarios and six violence categories are the research
+paper's Appendix B glossary, copied verbatim into merge-output/DEFINITIONS.md together with the
+database owner's clarifications on the Detention flag (2026-09-06/07). Use that file; do not
+paraphrase it elsewhere. The point that keeps biting: the DB field `kidnappings` is the DETENTION
+violence category (anyone held against their will, restrained, or prevented from leaving, for any
+length of time, including forced entry followed by beating or holding the victim in place), not
+the Kidnapping scenario (victim taken away to a controlled location).
