fix(aura-research, aura-cli, aura-runner): milestone-fieldtest bugs — the unwired ramp hole + three diagnostics

RED-first fixes for the four M42 A/B findings. campaign introspect
--unwired now drills into a present-but-empty presentation section
exactly as it drills into data, listing persist_taps/emit as open slots
— the miss caused three of the cold start's five dead ends (the process
sibling has no analogous nested-required shape, verified). The override
panic catch wraps known non-diagnostic payloads (capacity overflow) in
domain prose while passing real constructor messages through
byte-identical; a kind-mismatched override renders as prose naming
path, expected and got kinds with a write-this example instead of the
ParamKindMismatch debug struct; chart's unknown-handle refusal names
the current trace surface (exec --tap / presentation.persist_taps)
instead of the retired --trace flag.
