v0.2.10

Added

• Noise simulation API — NoiseModel class for per-qubit Pauli noise channels (depolarizing, dephasing, bit-flip, custom)
• noisy_estimate — analytical Pauli channel damping with zero simulation overhead for fast ansatz noise screening
• noisy_estimate_montecarlo — gate-by-gate Monte Carlo noisy estimation for accurate depth-dependent noise simulation
• noisy_execute — Monte Carlo shot-based noisy circuit execution with batched noise realizations
• Noise model helpers: set_depolarizing, set_dephasing, set_bit_flip, set_pauli_channel, set_all_depolarizing
• Comprehensive noise test suite (25 tests covering NoiseModel, analytical damping, Monte Carlo estimation, and execution)
• Noise simulation section in TUTORIAL.md with usage examples and parameter reference
