/**
 * Entity Resolver: turn an {@link Intent}'s raw slots into grounded values against
 * the schema, the live state, and conversation memory. Column names are matched
 * exactly, then case-insensitively, then by a bounded fuzzy match (so "reginn"
 * resolves to "region"); filter operators map to a valid per-column operand; values
 * are typed per the column; a bare "reverse" reads the active sort; and pronouns
 * ("it" / "those") resolve against `memory.lastEntities`. Errors are collected, not
 * thrown, so the planner can degrade to a helpful no-op.
 *
