Fixed gas limits in LayerZero cause transaction and fund locks

The LayerZero integration used hardcoded gas limits on the destination side. If the destination chain's gas profile shifted (opcode reprice, congestion, application change), bridged messages could fail to execute and funds could be stuck pending manual rescue.

Make destination gas limits configurable per route and per message type. Add adaptive gas estimation, or expose a re-execution path that lets users supply a fresh gas limit if the initial value is insufficient.
