Tests: v2 routing, single-vault withdraw, totalAssets view, transfer re-attribution

• Deposit routes via affiliates(user) and records underlying shares
• Withdraw resolves to a single vault and reverts when insufficient
• totalAssets sums convertToAssets across wrapper-held positions in tracked vaults
• Transfers proportionally re-attribute underlying shares (no external calls)

Test plan:

• Run: bunx hardhat test test/rewards/SendEarnRewards.erc4626.spec.ts

Revert per-user transfer re-attribution; remove _update override

Why:

• Transfers no longer re-attribute underlying shares; we will update flows and
  asset mappings only on deposit/withdraw/redeem per the corrected docs
• Remove per-user active vault tracking used only for re-attribution

Test plan:

• Compile

Docs: expand CFA v2.1 into professional spec

• Purpose/scope, definitions, dependencies, state model, invariants, resolution
• Triggers, placeholder policy, lifecycle flows with precise steps
• Rounding/safety/observability/failure modes/implementation notes/open items

Test plan:

• Render docs; verify sections and step details
