CI signs the image digest of each agent and probe release; the panel only
stores and forwards it. Nodes write the manifest to their data directory and
a host updater verifies the signature with a local public key, pulls by
digest, restarts the unit and rolls back when it is unhealthy. The panel can
list releases, ask a node to update and show the reported update state.
Agent and probe images were built with a restore step that lacked
PublishAot, so the publish silently produced a trimmed launcher that looks
for a .dll. Restore now passes PublishAot and the build fails if the binary
is smaller than 2 MB. Also add agent and probe compose files and document
the [CI] marker in AGENTS.md.
Squash of recent dev work: return_session login, backend switcher, line
detail timeline, overview strips, node platform/country/ISP info with flags
and icons, build info (version, tag, time) behind site.show_build, and the
acrylic display theme.
