Clarify provider vs integration terminology and document the in-tree
distribution model. Refresh M9 status, issue tracking, and lint/doc
links to
use the new language.
Rewrite the README around purpose, architecture, quickstart, and
status. Add contributing/security policies plus a docs index with
audience front matter across existing docs.

(ListDeliveringGrantsByOrgID) in member plan logic. Add documentation
and
status updates clarifying the lifecycle vs delivery distinction, include
a snapshot caveat, post-7e hotfix notes, and file an issue for
Transition.End reapplying defaults unexpectedly.
