/**
 * Use Expression Evaluation
 *
 * Handles `use<scheme:resource>` expressions:
 * - Resolves identifiers (static, variable, computed) to scheme + resource
 * - Looks up registered resolvers from ctx.resolvers
 * - Detects circular resolution via ctx.resolvingSchemes
 * - Executes 'source' results in a child scope
 * - Returns 'value' results directly
 *
 * Interface requirements:
 * - evaluateUseExpr(node) -> Promise<RillValue>
 *
 * Error Contracts:
 * - RILL-R054: Scheme not registered in resolvers
 * - RILL-R055: Circular resolution detected
 * - RILL-R056: Resolver callback throws
 * - RILL-R057: Variable/computed form produces non-string
 * - RILL-R058: Resolved string missing ':' separator
 * - RILL-R061: parseSource not configured when resolver returns source
