Module sql 

Compile GQL AST to parameterized SQL.

Two compilation paths:

• Fixed-length patterns (all edges *1..1) → JOIN chain
• Variable-length patterns (any edge *N..M where M>1) → recursive CTE

Security invariants (MAJ-1/MAJ-2/MAJ-3 from critic review):

• Namespace injection: WHERE clause always comes from CompileOptions.scopes, never the query.
• Edge property whitelist: only relation and weight are queryable edge columns.
• Depth cap: recursive CTE depth is min(requested, 10).
