chore: implement atomic vault migration adapter

[V00D00-child]

What?

• Add VaultMigrationAdapter to compose existing base (VedaAdapter) and premium (ComplianceVedaAdapter) calls into one atomic transaction
• Support to-premium and to-base as permissionless single and batch entry points, forwarding both delegation chains and premium deposit compliance

Why?

• To support money account atomic vault migrations(ie to-premium / to-base)

How?

• Original Veda adapter: chore: Implement VedaAdapter #166
• Compliance veda adapter: chore: implement compliance veda adapter #205

Note

High Risk
Moves vault shares and underlying assets through permissionless entry points with custom compliance and delegation signature schemes; bugs could affect user funds or allow mis-routed premium transfers.

Overview
Introduces VaultMigrationHelper, a compositor over immutable VedaAdapter and ComplianceVedaAdapter so base ↔ premium vault moves run as one atomic transaction via paired withdrawal/deposit delegation chains (single and batch, permissionless callers). To-premium legs still forward premium deposit compliance to the compliance adapter; shared root delegator and slippage checks are enforced in the helper.

Also adds premiumTransfer / batch: redeems a leaf delegation that sends the owner’s full premium share balance to the helper, then forwards shares to a to address only after dual destination control—ERC-1271 EIP-191 user proof binding from/to/leaf signature, plus a helper-scoped compliance EIP-191 digest (replay-protected, Teller signer role/window, distinct from deposit signatures). Owner withdrawEmergency recovers stray tokens.

Deployment is supported via DeployVaultMigrationHelper.s.sol (CREATE2 + new .env vars) and IComplianceVedaTeller / IRolesAuthority interface additions for compliance role checks. Broad Monad fork tests cover migrations, batches, transfer edge cases, and compliance failures.
