compile_filters() unconditionally appended 'deprecated_by IS NULL' to
every query, but the deprecated_by column only exists on user-scoped
tables (episode, atomic_fact — Reflection V1). Agent tables
(agent_case, agent_skill) lack this column, causing a SQL error on
agent search/get queries.
Gate the clause behind owner_type == 'user' so agent queries no longer
reference a non-existent column.
Bump version to 1.1.2.
