zeekay 8feb24ea1f One name for this fork, and it is ours
The server module named github.com/hanzoai/team/server/v8 — a path that
resolves to the retired workspace's repository, not this one — while
server/public still published github.com/mattermost/mattermost/server/public.
Both are github.com/hanzoteam/server/... now, which is where this code
actually lives.

That second half is what made the binary unbootable. Upstream's public path
stayed claimed by upstream, mattermost-plugin-ai imported it, and the build
linked public/model twice; public/plugin's gob.Register then ran twice under
one name and panicked at init, before main. Reverting the rename traded the
brand for a working binary. Rebranding the plugin alongside it needs no such
trade: the agents fork is github.com/hanzoteam/agents/v2 against our public
module, so no module named mattermost/mattermost is in the graph at all.

Measured: `go list -deps ./cmd/mattermost` names exactly one public/model, and
it is ours.
