P3: Update TaskStore to synchronous API and test improvements

- Remove .await from TaskStore trait methods (synchronous API) - Update testcontainers to AsyncRunner for Redis tests - Add sha2::Digest import for idempotency tests - Update all test files to use synchronous TaskStore API Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>
