This enables tree-shaking by having each operator register its own evaluator when imported, rather than relying on a monolithic switch statement. Key changes: - Add registry.ts with registerOperator/getOperatorEvaluator APIs - Create individual operator files (eq, gt, gte, lt, lte, and, or, not, in, like, ilike, upper, lower, length, concat, coalesce, add, subtract, multiply, divide, isNull, isUndefined) - Each operator file bundles builder function + evaluator + registration - Modify evaluators.ts to use registry lookup instead of switch - Update query/index.ts to export from new operator modules - Export compileExpressionInternal for operator modules to use The pattern: importing an operator causes its file to execute, which calls registerOperator, adding it to the registry. By query compile time, all operators in use are already registered.

Export the registry API so users can create and register their own custom operators. Also adds a changeset for this patch.
- Export registerOperator, EvaluatorFactory, and CompiledExpression types - Add comprehensive tests for custom operator registration - Tests cover between, startsWith, isEmpty, modulo operators - Demonstrates full pattern: builder function + evaluator + registration
Extend the auto-registration pattern to aggregates (sum, count, avg, min, max): - Create aggregate-registry.ts with registerAggregate/getAggregateConfig - Split each aggregate into its own module with builder + auto-registration - Update group-by.ts to use registry lookup instead of switch statement - Export registerAggregate and types from public API - Add tests demonstrating custom aggregate registration This enables tree-shaking for aggregates and allows users to register custom aggregates like 'product', 'variance', etc.
- Remove eager imports from evaluators.ts and group-by.ts - Make functions.ts re-export from operator/aggregate modules - Add shared types.ts for type helpers preserving nullability - Update test files to import operators for direct IR testing Now operators/aggregates are only loaded when user imports them, enabling true tree-shaking. The compiler no longer pre-loads all evaluators - they register when their builder functions are imported.
Replace global registry pattern with embedded factories for true tree-shaking: - Func nodes now carry their evaluator factory directly - Aggregate nodes now carry their config (factory + valueTransform) directly - Remove registry.ts and aggregate-registry.ts files - Update all operators to pass factory as 3rd argument to Func - Update all aggregates to pass config as 3rd argument to Aggregate - Update internal code (optimizer, predicate-utils, expressions) to preserve factories when transforming Func nodes - Add array overloads to and() and or() for internal usage - Update tests to use builder functions instead of creating IR directly This design eliminates the need for side-effect imports and ensures only imported operators/aggregates are bundled.
