Fix Python 3.10 incompatibility: replace UTC with timezone.utc

[Copilot]

datetime.UTC was introduced in Python 3.11 and is unavailable in Python 3.10, causing an ImportError in CI.

Changes

• jl_engine_core/engine_core.py: Replace UTC (Python 3.11+) with timezone.utc (Python 3.2+)

# Before
from datetime import UTC, datetime
datetime.now(UTC)

# After
from datetime import datetime, timezone
datetime.now(timezone.utc)

Original prompt

The CI is failing due to ImportError: cannot import name 'UTC' from 'datetime' because UTC is not available in Python 3.10. Fix the import in jl_engine_core/engine_core.py by changing line 37 from 'from datetime import UTC, datetime' to 'from datetime import datetime, timezone', and update the usage of UTC to timezone.utc in the _append_feedback_log method.

The following is the prior conversation context from the user's chat exploration (may be truncated):

User: Dude can you fix this shit man

Assistant: I analyzed the failing Actions run for PR #3 in jaden688/JL_Engine-local. The issue is an ImportError in jl_engine_core/engine_core.py: UTC isn't available in Python 3.10 (used by the CI runner), only from 3.11 onward.

I've created a pull request to fix this by updating the import to use timezone.utc instead, which is compatible with Python 3.10. This should resolve the test failures.

You can review and merge the PR here: JL_Engine-local PR #4 (assuming it gets created; check your repo for the new PR).

If you'd prefer a different approach or need help with anything else, let me know!
