Selecting a command showed no output because Execute built the
RuntimeContext as a bare struct literal (&RuntimeContext{Args: args}),
leaving Client == nil. Any command calling ctx.CallAPI then panicked with
a nil pointer dereference inside the executor goroutine; the panic aborted
the goroutine before w.Close()/stdout restore, so the execResultMsg never
fired and the REPL hung silently.
Fix: use common.NewRuntimeContext(args) (initializes Client/Format/Owner/Repo,
matching runner.go), and wrap s.Run in safeRun() so a panic converts to an
error and stdout is always restored.
Adds regression tests: nil-Client assertion, panic-safe stdout restore, and
an end-to-end test that runs the real repo +list shortcut and asserts
Execute never returns (empty output, nil error).
Previously the palette only opened after pressing Enter because the trigger
logic lived in the KeyEnter branch. The spec requires '/' to open the palette
immediately. Now KeyRunes with '/' as the first character of an empty input
switches to statePalette right away, carrying any trailing characters (e.g.
'/iss') as the initial search query.
Adds regression tests covering: immediate '/', '/' with query, and ordinary
text staying in input state.
