Query pre-cached objects in SelectObjects

[joshlit]

What changed

• route SelectObjects and MultipleSelectObjects queries to the in-memory pre-cache for tables with PreCache = true
• evaluate structured WhereClause expressions against cached objects, including comparisons, AND/OR, IN, LIKE, null checks, ordering, and limits
• cache column-to-binding lookups and reuse LIKE matchers to keep cached filtering efficient
• add focused tests proving query results are correct and incur zero database connections

Why

Previously, UsesPreCaching only affected key lookups and select-all calls. Filtered SelectObjects calls still queried the database even though the complete table was already held in memory. This makes filtered and batched selects consistently honor the pre-cache and avoids unnecessary database round trips.
