fix(ui): null-guard agent access and refocus input after token insert

Browse Source 
AgentMap.Instance() and AgentChatLog.Instance() can return null during
zone transitions. Capture pointers into locals and short-circuit the
FlagMarkerCount/LinkedItem deref when null so the entries are correctly
greyed out without faulting. Add Activate/ActivatePos after each append
so the input box regains focus and the caret lands after the token,
matching the SymbolPicker and AutoComplete insert paths.
