Module types 

Shared DynamoDB types for the 12 MVP operations.

All types follow the DynamoDB JSON wire format with PascalCase field names. Structs use #[serde(rename_all = "PascalCase")] to match the DynamoDB API.

Enum variants use idiomatic Rust PascalCase naming with #[serde(rename)] attributes to map to the SCREAMING_SNAKE_CASE wire format that DynamoDB uses.

MVP Operations Covered

• Table management: CreateTable, DeleteTable, DescribeTable, ListTables
• Item CRUD: PutItem, GetItem, UpdateItem, DeleteItem
• Queries: Query, Scan
• Batch: BatchGetItem, BatchWriteItem
