- PR #91075: fix(state): collapse stacked/adjacent FTS5 boolean operators instead of a silent empty search

Three members concern session search returning empty results when queries contain stacked or adjacent FTS5 boolean operators (e.g. "a AND OR b", "AND NOT x"). Two are fix proposals that collapse such operators in the state and agent areas, and one is the issue describing the silent empty result.
