fix(direct): resolve SDK modules from the current genlayer.py layout

[HusseinAdeiza]

What

gltest/direct/sdk_compat.py imported the SDK's calldata and types modules from the package root:

from genlayer import calldata
from genlayer import types as sdk_types

The SDK moved both under genlayer.py in 0.6. On a 0.6 runner those imports raise ImportError, and _inject_message_to_fd0 swallows it:

try:
    calldata = import_calldata()
    Address = import_address()
except ImportError:
    return

So the encoded message is never written to fd 0, and the SDK decodes real stdin at import time instead — surfacing as a decode error against a contract that never got its context:

ImportError: Failed to load contract: unexpected end of memory

Not specific to Address constructor args

I reproduced on 0.30.0rc2 / 0.19.0rc2 and the failure covers every constructor shape I tried, no-arg included:

Constructor	Result
()	fails
(a: u256)	fails
(a: Address)	fails
(a: Address, b: Address)	fails
(a: DynArray[str])	fails

The two-Address constructor is just the smallest case, which is likely why it read as type-specific.

Fix

Import from the current location, falling back to the legacy one so older pinned runners keep resolving:

def _import_sdk_module(name: str) -> Any:
    try:
        return importlib.import_module(f"genlayer.py.{name}")
    except ModuleNotFoundError:
        return importlib.import_module(f"genlayer.{name}")

Testing

• tests/gltest_direct: 58 passed (52 before, plus 6 new).
• Full suite unchanged at 22 pre-existing failures / 2 errors in tests/examples and tests/test_bug_hunt_v030.py, identical before and after.
• Each new test fails on the unpatched tree and passes with the fix.

The reporter's related question about cross-contract calls in direct mode is untouched here — that path needs a _gl_call_hook and is a separate question.

Fixes #113
