fix: bump eth-account minimum version to >=0.13.5

[vinayyak]

Summary

The Hyperliquid client expects LocalAccount.sign_typed_data (EIP-712) to exist, but older eth-account releases (e.g. 0.10.x) do not expose that method. As a result, calls to sign_l1_action fail with:

AttributeError: 'LocalAccount' object has no attribute 'sign_typed_data'

Where the error occured:

  File "/app/.venv/lib/python3.12/site-packages/hyperliquid/utils/signing.py", line 216, in sign_l1_action
    return sign_inner(wallet, data)
           ^^^^^^^^^^^^^^^^^^^^^^^^
  File "/app/.venv/lib/python3.12/site-packages/hyperliquid/utils/signing.py", line 395, in sign_inner
    signed = wallet.sign_typed_data(full_message=data)
             ^^^^^^^^^^^^^^^^^^^^^^
AttributeError: 'LocalAccount' object has no attribute 'sign_typed_data'

Bump the minimum eth-account version so that EIP-712 signing is guaranteed to work.

Changes

In pyproject.toml, replaced:

- eth-account = ">=0.10.0,<0.14.0"
+ eth-account = ">=0.13.5,<0.14.0"

Rationale

Versions of eth-account prior to 0.13.5 lack the LocalAccount.sign_typed_data method. Hyperliquid’s sign_l1_action calls wallet.sign_typed_data(...) under the hood, so we must require a release that implements EIP-712 “typed data” signing. Pinning eth-account >=0.13.5 ensures compatibility without breaking other dependencies.

Testing

Opened a Python REPL (using the locked environment):

1. Then verified if older version contains the sign_typed_data method, which is did not:

>>> from eth_account import Account
>>> acct = Account.create()
>>> hasattr(acct, "sign_typed_data")
False
>>> dir(acct)
['__abstractmethods__', '__bytes__', '__class__', '__delattr__', '__dict__', '__dir__', '__doc__', '__eq__', '__format__', '__ge__', '__getattribute__', '__getstate__', '__gt__', '__hash__', '__init__', '__init_subclass__', '__le__', '__lt__', '__module__', '__ne__', '__new__', '__reduce__', '__reduce_ex__', '__repr__', '__setattr__', '__sizeof__', '__slots__', '__str__', '__subclasshook__', '__weakref__', '_abc_impl', '_address', '_key_obj', '_private_key', '_publicapi', 'address', 'encrypt', 'key', 'signHash', 'signTransaction', 'sign_message', 'sign_transaction']

2. Checked against the Latest Client Version after updating

3. Re-tried and confirmed that it now contained the method:

>>> from eth_account import Account
>>> acct = Account.create()
>>> hasattr(acct, "sign_typed_data")
True

Please let me know if any modifications are needed.
