Subject: [PATCH] fix(search): include Library source filter in shareable URL

The new library_source provenance filter wasn't serialised into the Share-view URL, so a
copied link lost the 'search results only' (or 'include search') selection. Add it as the
'source' param (emitted only in 'all' scope, omitted for the default 'organic').
