"""TDD Tests for Solana adapter enhancements (Phase 7).

Tests cover:
- 7.1 Memo injection: MockSolanaAdapter returns memo field
- 7.1 Memo injection: SolanaAdapter builds transaction with Memo instruction
- 7.2 ATA auto-creation: SolanaAdapter checks & creates ATA when needed
- 7.3 Transaction confirmation: SolanaAdapter waits for confirmation
