Pull request overview

Adds support in dsw-data-seeder for configurable placeholder variables (and named UUID placeholders) that can be substituted into seed SQL scripts, with configuration exposed via recipe JSON and app config.

Changes:

• Extend seed recipe format to support uuids.names and variables (placeholder + values).
• Add variable/UUID placeholder replacement logic to SeedRecipe and wire recipe loading to merge configured variables.
• Introduce seed configuration section (job timeout + variables) and add cast_dict helper in dsw-config.

Reviewed and addressed the remaining unresolved issue: seed.variables could be None when the config key used cast_optional_dict, causing AttributeError on .copy() in seeder.py even with the contextlib.suppress(ContextNotInitializedError) guard in place. Fixed in fe996ef by changing the config key to use cast_dict instead of cast_optional_dict, ensuring variables is always a dict (empty {} when not configured) — consistent with the SeedConfig.variables: dict type annotation.
