Module overlay_transformer 

Name transformation for mz-deploy dev overlay compilation.

This module provides OverlayTransformer, which implements the two-step reference resolution rule for schema-level overlays:

1. External references — if the database is not in in_project_databases, emit the name verbatim.
2. Dirty schemas — if (database, schema) is in dirty_schemas, rewrite the database component to <database>__<profile_name>. Otherwise emit <database>.<schema>.<object> (production reference).

Unqualified / partially qualified names are fully qualified using the transformer’s fqn context before the rule is applied.

The project planner has already applied any configured profile_suffix to database and cluster names before dev invokes the transformer, so no suffix handling is required here.
