fix(cmdatom): lhs not always reported in CmdAtom #41386

Problem:
An unreplayable Visual operation does not emit a CmdAtom event. That's
maybe not super important, but it hints at a flaw in how `vatom`
"voiding" is plumbed: `vatom.state=kVatomVoid` replaces the "kind", so
that info is lost to later parts in the lifecycle.

Solution:
- Define `VatomState` as "flags", so `kVatomVoid` can "poison"
  `vatom.state` without losing its kind flag.
- Unify `lhs`: always report the original user input in `CmdAtom.lhs`,
  for all kinds of user actions: visual, "translated"/"stuffed" cmds,
  and dot-repeat (".") itself.
- Unreplayable Visual atom emits CmdAtom with non-empty `lhs` and empty
  `keys`, like a mapping/macro composite.
