feat(circuits): add Circuit.from_pyquil import

[jesusblls]

Closes #4.

Summary

• add Circuit.from_pyquil() for importing concrete pyquil.Program instances
• map the canonical Marqov gate set including rotations, CNOT/CZ, and native SWAP
• reject unsupported Quil-native gates with NotImplementedError
• add an optional pyquil extra and include it in all

Tests

• .venv312/bin/python -m pytest tests/test_circuits.py::TestFromPyQuil -q -> 6 passed, 18 warnings
• .venv312/bin/python -m ruff check marqov/circuits.py tests/test_circuits.py pyproject.toml -> All checks passed
• .venv/bin/python -m py_compile marqov/circuits.py tests/test_circuits.py -> passed
• git diff --check -> clean

Thanks for the PR. I see your account is set up to focus on bounties. Have you registered for the unitaryHACK event? And did you follow the instructions at the bottom of the GitHub Issue?

The concern here would be that AI has done all the work, and there's not been any good-faith effort to really understand the project, make thoughtful decisions, and properly test the solution in context.

To help me understand if that's the case, I'd like to hear your thoughts on this, and talk a little about your experience and approach using the Marqov SDK.
