Switching to another saved specialization never confirms a build, so
CHARACTER_ADVANCEMENT_UPDATE_ENTRIES_RESULT doesn't fire for it and the
cached talent state stayed stale for the rest of the session. That path
only fires PENDING_BUILD_UPDATED and SUGGESTIONS_UPDATED, so listen to
both. PENDING_BUILD_UPDATED also fires on every click inside the talent
UI, so the handler recomputes the cached rank and rebuilds the
unitframes only when the answer actually changed.
Also fall back to matching the talent by name among the learned entries
when the entry ID reports nothing, so an ID gone stale after a server
rebalance doesn't silently switch the feature off.
