docs: add source-available license pack and public contributor guides

Phase A of the OSS-ready program: LICENSE (official PolyForm Noncommercial
1.0.0 with Required Notice) and NOTICE (first-party excluded assets vs
third-party materials governed by their own embedded terms, nominative-use
statement, commercial contact); license fields in all 29 manifests with the
root description now source-available; the five MIT-claiming skills aligned;
AGENTS.md rewritten from scratch as the canonical public guide with private
operator prose removed; CLAUDE.md as a thin @AGENTS.md import; Contributor
Covenant 2.1, issue forms, and a PR template with verification notes; one UI
comment reworded to its real constraint.
