Module nms_eval 

Async eval bridge for the Console tab.

ConsoleEval is a concrete (no dyn) actor: it owns an mpsc to a per-console worker that drives rpc::Session::handle_form, plus the cancel handles (EpochBumper + InterruptHandle). The UI side is sync — submit is a non-blocking send, drain a try_recv loop — so the 200 ms run_loop never awaits eval.

Session::handle_form parses an RPC request envelope ((:id N :form <form>)), not a bare form, so submit wraps each input with a monotonic id before handoff — mirroring nms’s RpcEval::eval and the sshd eval_channel worker. The worker receives already-wrapped envelopes and only forwards them.

Two constructors form the test seam: ConsoleEval::spawn builds a real DB-backed Session actor, while ConsoleEval::echo spawns a runtime-only worker that echoes frames back (no Session, no DB) for plumbing tests.
