Commit Message

Merge pull request #348 Gate refactor

Refactor gate architecture (fixes #263).

- Standardize on `add_gate(GateSubclass, ...)` as the long-term API.
- Deprecate string-based gate insertion (old method 2); remove support for direct `Gate(...)` instantiation and pre-built gate-object insertion in the next release.
- Make `Gate` abstract and split circuit placement data (`targets`, `controls`, cbits, style) into instruction objects.
- Replace `QubitCircuit.gates` with `QubitCircuit.instructions`.
- Add modular gate helpers: `get_unitary_gate` and `get_controlled_gate`.
- Move legacy function-style gates to `old_gates.py` and deprecate them.
- Remove/deprecate legacy circuit APIs (`add_1q_gate`, `add_gates`, `adjacent_gates`, `index` arg, etc.).
- Add typed gate hierarchy (`ParametricGate`, `AngleParametricGate`, `ControlledGate`) and stricter validation.

Implementation and design details were discussed across #307, #308, #309, #316, #319, #325, and #328.
