Support enum mapping for slots with multiple enum ranges (any_of)

[amc-corey-cox]

Summary

• Slots using any_of to specify multiple enum ranges are now correctly transformed
• transform_enum accepts a list of enum names and iterates in order until a match is found
• Enum handling integrated into _map_value_by_range — values flow through the normal coercion/reshaping pipeline (no continue hack)
• Handles both range: None and range: Any with any_of enum ranges
• Add _get_any_of_enum_names static method to extract enum names from any_of constraints
• Clean up stale EXTRACT markers and step comments from prior refactor

Closes #146

Test plan

• 13 new enum-specific tests (single-valued, multivalued, container, mirror_source, no match, null)
• All 124 transformer tests pass
• Lint and format clean

Pull request overview

Adds support for mapping enum-valued slots whose source schema expresses multiple enum ranges via any_of, by extracting enum names from slot.any_of and trying enum derivations sequentially until a match is found.

Changes:

• Update ObjectTransformer.map_object to detect enum ranges in any_of (when slot range is missing) and route values through enum transformation.
• Extend transform_enum to accept an ordered list of enum names and try each derivation in order (respecting mirror_source short-circuit).
• Add a comprehensive test suite for multi-enum (any_of) enum mapping behavior.
