feat: optimize contract size under 24KB by removing duplicate public methods

- Remove redundant public getter methods that duplicate IWormhole trait functionality
- Eliminate Result wrapper overhead and repeated initialization checks
- Contract size reduced from 24.7 KiB to 24.0 KiB (24,561 bytes)
- Successfully under Arbitrum 24KB compressed limit (24,576 bytes)
- All 27 unit tests continue to pass
- Complete Wormhole functionality preserved (VAA parsing, signature verification, guardian sets)
- Ready for Arbitrum deployment
