Bring in the natural-key import fix, Metrics->Monitors rename, PC detail tabbing and panel groups, guest search grants, and the 2026-08-30 security fixes. Reconcile endpoint packaging/installer, migrations, contract version, and tests; keep the delivery uninstaller and 6-step installer alongside main's permission-based RBAC and pin-drift protection.
Ben Baker's installed-software collection, software delivery (run_script and
update_app), agentless adoption tool and command-queue hardening, with his
authorship preserved.
Reviewed before promotion. Fixed: the endpoints plugin tests were never collected
by pytest, the SBOM snapshot table's key would exhaust on MySQL, ingest did not
truncate two columns strict MySQL would reject, and update_app's version branch
pinned a digest for a file that route never serves. Agent packaging moved off
require_role('admin') onto a new endpoints.agentpackage permission.
Contract 0.27.0. Full suite 2231, frontend 314.
