imccyu 76796df39b test: close the two coverage tails on the plan surfaces
The plan unit's same-reference gate for a repeated identical /plan selection
(the one uncovered branch in plan-mode/index.ts) gains an explicit case, and
ui-plan's empty node-half apply is exercised the way sibling surface plugins
do (the ui-conversation no-op precedent). Both files read 100% across all
four axes under the CI coverage lane's per-file thresholds.

/**
* ui-plan browser half on a real SlotsService: the plugin occupies the
* conversation-declared `conversation.input.plan` single seat; the injected
* face maps mode selections onto /plan command lines and folds admission
* outcomes into null (admitted) or a user-visible failure line; teardown
* empties the seat (HMR safety).
