Closes #975

Summary

Implements MultiSigCoordinator — a coordinator for collecting signatures from multiple Stellar signers before transaction submission.

Changes

  • src/multiSignature.ts: Core implementation
  • test/multiSignature.test.ts: Comprehensive test suite

Features

  • MultiSigCoordinator — create sessions, collect signatures, enforce weight thresholds
  • computeAccumulatedWeight / isThresholdReached — utility functions
  • Per-signer weights, duplicate-signature prevention, session expiry
  • Event emission: signature:added, threshold:reached, session:expired, session:rejected
  • Validation: unauthorized signers, threshold reachability, session state guards

Acceptance Criteria

  • Feature implemented
  • All tests pass
  • TypeScript compiles with zero errors
  • ESLint passes
