chore: convert guru-connect to submodule; integrate ADR-008 + 2026-05-29 session log

guru-connect is now tracked as a submodule (azcomputerguru/guru-connect @ e3e95f8);
its working state was published to the GC repo first, so no content is lost. guru-rmm
advanced to include ADR-008 (GC integration boundary) replayed on top of the team's
Integrations Center / discovery advances. Includes the native-remote-control spec
(now inside the GC submodule), the versionable-products memory, and the session log.
