v2.10.0

FiQueLa version 2.10.0 is now available!

Added

• DESCRIBE clause for inspecting data source schema — returns column names, types, statistics (confidence, completeness, uniqueness, enum detection).
• DescribeResult class extending ResultsProvider with single-pass column analysis.
• Describable trait with isDescribeMode(), isDescribeEmpty(), and enableDescribe().
• AggregableResult interface extracted from Results interface for sum(), avg(), min(), max().
• Blocking mechanism in traits (Select, Conditions, Groupable, Sortable, Limit, Joinable, Unionable, Explain) — DESCRIBE is mutually exclusive with SELECT, WHERE, GROUP BY, ORDER BY, LIMIT, JOIN, UNION, EXPLAIN.
• FQL SQL support: DESCRIBE json(file.json).data.products.
• Debugger highlighting for DESCRIBE keyword.

Fixed

• ORDER BY now supports nested fields via dot notation (e.g. orderBy('brand.code')) — previously only flat keys were accessible.

Changed (BREAKING)

• sum(), avg(), min(), max() removed from Interface\Results — moved to new Interface\AggregableResult.
• Stream and InMemory now implement AggregableResult interface explicitly.
