v0.4.0 — ERC-20 and ERC-4626 vesting

Version 0.4 separates ordinary token vesting from ERC-4626 principal and yield accounting behind one immutable factory.

Highlights

• Dedicated minimal-proxy implementations for standard ERC-20 and ERC-4626 escrows.
• Asset-denominated ERC-4626 vesting with an explicit maximum share spend and a fixed yield recipient.
• Clear recipient, revoker, receiver, funder, and yield-recipient roles.
• Immediate revocation to an explicit receiver, revocation renunciation, and permissionless claims with fixed routing.
• Versioned creation events as the canonical discovery mechanism, without a duplicate on-chain registry.
• Modern Vyper 0.4.3 and uv development workflow, with full API, accounting, integration, and deployment documentation.
