In the remove-wizard's confirming state, pressing Esc was reflexively
calling removeForwardsCmd — i.e. confirming deletion. The on-screen
help text said 'Esc: Cancel'. Reflexive Esc-to-cancel destroyed data.
Esc now sets confirming=false and resets the cursor; deletion
requires Enter on Yes. Non-confirming Esc behavior (exit wizard with
ClearScreen) is unchanged.
Three regression tests added in handlers_test.go.
P0 #2 — currentConfig data race
Manager.currentConfig was written without locking in Start/Reload but
read from the health-checker callback goroutine. All accesses now go
through workersMu (read or write as appropriate).
P0 #3 — Reload kills health checker permanently
Reload's zero-forward branch called m.Stop() which tore down the
health checker, watchdog, and event bus. After that, EnableForward
silently registered callbacks against dead components. Now the branch
stops only the running workers; the supervisory infrastructure stays
alive across config changes.
P0 #4 — rest.Config write-write race
executePortForward was mutating .Dial on the cached *rest.Config
shared by all forwards in the same kube context. Cloning the config
with rest.CopyConfig before mutation isolates per-forward dialers.
P0 #5 — ForwardWorker.Stop() double-close panic
close(w.stopChan) is now wrapped in sync.Once, so concurrent Stop
calls (Manager.Stop racing stopWorkerInternal) are safe.
New tests in internal/forward/concurrency_test.go exercise each fix
under -race: 16 concurrent worker Stops, repeated sequential Stops,
empty-Reload preserves infra pointers, and concurrent currentConfig
read/write.
CI runners have no kubeconfig, so clientcmd's loader returns an empty
config (no error) and CurrentContext == "". The previous assertion
'NotEmpty(context)' on the success branch was incorrect — an empty
current-context is valid for an empty kubeconfig.
Mirrors the looser pattern in TestDiscovery_ListContexts.
