Add FireHorseConsumer Chainlink signal consumer contract

[jpbpari-sys]

Motivation

• Provide a minimal on-chain Chainlink consumer that decodes an oracle-encoded trading signal into LONG/SHORT and expose an owner-gated hook for future DEX execution.

Description

• Add FireHorseConsumer.sol which includes SPDX and pragma, imports AggregatorV3Interface, stores oracle and owner, implements getSignal() mapping answer == 1 to "LONG" and otherwise "SHORT", and provides an autoTrade() owner-only stub for integrating DEX logic.

Testing

• No Solidity toolchain is configured in this repository, so no compilation or automated Solidity tests were executed.

Validate oracle answers instead of defaulting to SHORT

getSignal() maps every non-1 response to "SHORT", so any unexpected oracle value (for example 0, 2, or a temporary bad payload) is treated as an active short signal. In contexts where autoTrade() will execute positions, this can flip strategy decisions on invalid data rather than failing safely; handle only explicitly supported encodings and revert/hold for anything else.

Reject invalid oracle address at deployment

The constructor accepts _oracle without validation, so a misconfigured deployment (e.g., address(0) or a non-aggregator address) will leave the contract unable to return a signal because latestRoundData() cannot be decoded as expected. Failing fast in the constructor with an address/code check prevents shipping a permanently broken consumer.
