Locker Migration Implementation

Overview

This PR implements a migration system to transfer existing locker tokens from the old contract to the new BaseLocker implementation while preserving all lock details and ownership.

Key Changes

Migration Logic (BaseLocker.sol)

• Added migrateLock() and migrateLocks() functions
• no MAHA transfer needed
• Preserves:
  • Amount
  • Start/end times
  • Power
  • Ownership

Deployment (deploy-migrate.ts)

• Deploys LockerToken-V3 and OmnichainStakingToken-V3
• Proper initialization and contract linking

Migration Data (locker-snapshot.csv)

• 1,109 tokens with complete lock data
• Fields:
  • token
  • amount
  • start
  • end
  • owner
  • stakednft

Migration Script (migrate-locker.ts)

• Reads from CSV for efficiency
• Batch processing (100 tokens/batch)
• Handles both staked/unstaked tokens correctly

Testing (LockerMigrationTest.sol)

• Fork test with Base mainnet data
• Validates:
  • Amount
  • Start/end times
  • Power
  • Ownership
