Module graph 

Dependency-aware project graph.

Project is the final output of compilation — the result type of compile_sync. It combines a hierarchical view of the project with a flat dependency graph:

• databases — the database > schema > object hierarchy used for iteration, deployment ordering, and module-statement execution.
• dependency_graph — a flat adjacency list (ObjectId → {ObjectId}) used for topological sort, change propagation, and reverse-dependency lookups.
• external_dependencies — objects referenced by the project but not defined in it (e.g., pre-existing sources). These appear as values in dependency_graph entries but are excluded from topological sorts and deployment.
• cluster_dependencies and replacement_schemas — deployment metadata extracted during graph assembly.

Invariant: every ObjectId reachable through databases has an entry in dependency_graph. External dependencies appear only in dependency-set values and in the external_dependencies set.
