Versioned Layout & Tokens

Opinionated structure under a configurable root (default: tables):

tables/
  table.template.yml     # optional baseline for non-generated Properties
  001/
    entityManager.ts     # EM for this version (or fallback to earlier)
    table.yml            # full AWS::DynamoDB::Table resource
    transform.ts         # optional per-step transforms
  002/
    ...

Tokens (configurable)

table (table.yml)
entityManager (entityManager.ts/.js)
transform (transform.ts/.js)

Fallback EntityManager resolution

For each step, resolve both prev and next EM: try the version directory first; if missing, walk backward to the nearest version with entityManager present.
Required for the default chain (prev.removeKeys → next.addKeys).

Notes

Version directories are zero-padded (e.g., 001, 002).
File resolution supports .ts and .js for EM/transform modules.
