Pull request overview

This PR significantly improves test coverage by reorganizing the test suite into a more modular structure and adding comprehensive test coverage for utility functions, termination conditions, optimization results, integration wrappers, and acquisition functions.

Key Changes

• Reorganized acquisition function tests from a single monolithic file into separate test modules under tests/acquisition/
• Added comprehensive test coverage for previously untested modules (utils, termination, optimize_result, integrations)
• Introduced pytest markers (slow, integration, unit, docs, examples, convergence) to enable selective test execution
• Updated CI workflow to run fast tests on all platforms and slow tests only on Ubuntu with Python 3.11
• Refactored minimize_surrogate.py to use helper functions and eliminate nested function definitions
