Layer 1: Intent (qail-core)

The universal AST that represents all database operations

Component	Status	Description
Qail AST	100%	Core data structure for all query types
Builder API	100%	`.get() .filter() .order_by() .limit()`
Parser	100%	Text syntax → AST (for CLI, LSP, WASM)
Validator	100%	Schema validation with fuzzy suggestions
Formatter	100%	AST → canonical text (qail fmt)
