No ssh: git provider is registered in production, so the reconnect
coordinator's catalog and lineage reads always came back non-authoritative
and its worktree refresh never merged. Its only live effect was clearing an
unconverted target's stale PTY bindings on each connected push and on wake;
the state bridge now does that directly.
Deletes the coordinator, preparation, worktree refresh scheduler, host
hydration, rollout flag and their product telemetry event, the scoped
direct-SSH reconnect/hydration options, and the now caller-less
repos:listForExecutionHost and worktrees:listLineageForHost IPC handlers.
