fix: add missing chainId to inference transaction in _send_tx_with_revert_handling()

Bug Fix: Missing chainId in _send_tx_with_revert_handling() — affects all infer() calls

Summary

_send_tx_with_revert_handling() in alpha.py is missing chainId when building the inference transaction. Every other transaction in the same file includes it — this method was the only exception.

---

The Bug

# BEFORE — _send_tx_with_revert_handling (used by infer())
transaction = run_function.build_transaction(
    {
        "from": self._wallet_account.address,
        "nonce": nonce,
        "gas": gas_limit,
        "gasPrice": self._blockchain.eth.gas_price,
        # ❌ chainId missing
    }
)

Compare with every other transaction in the same file:

# new_workflow ✅
transaction = contract.constructor(*constructor_args).build_transaction(
    {
        ...
        "chainId": self._blockchain.eth.chain_id,  # ✅ present
    }
)

# run_workflow ✅
transaction = run_function.build_transaction(
    {
        ...
        "chainId": self._blockchain.eth.chain_id,  # ✅ present
    }
)

# _register_with_scheduler ✅
scheduler_tx = scheduler_contract.functions.registerTask(...).build_transaction(
    {
        ...
        "chainId": self._blockchain.eth.chain_id,  # ✅ present
    }
)

---

Impact

• _send_tx_with_revert_handling is called by infer() — the primary and most commonly used Alpha Testnet method
• Without chainId, Web3.py signs the transaction without EIP-155 replay protection
• Some RPC nodes reject transactions that lack chainId; others silently accept them but the transaction may be replayable on other chains
• This is an inconsistency that makes infer() behave differently from every other transaction in alpha.py

---

Fix

# AFTER ✅
transaction = run_function.build_transaction(
    {
        "from": self._wallet_account.address,
        "nonce": nonce,
        "gas": gas_limit,
        "gasPrice": self._blockchain.eth.gas_price,
        "chainId": self._blockchain.eth.chain_id,  # ✅ added
    }
)

@adambalogh @kylexqian — one-line fix that makes infer() consistent with every other transaction in the same file. 🙏
