optimize parameter processing and UUID conversion; enhance regex patt…

[h0rn3t]

This pull request introduces several performance optimizations and code simplifications for the psqlpy_sqlalchemy package, with a focus on parameter conversion, UUID handling, and efficient query processing. The changes leverage Python version-specific features for improved speed and maintainability, and also update the package version.

Performance and compatibility improvements:

• Refactored parameter and UUID conversion logic to use Python version-specific optimizations (e.g., direct class comparison, inlined comprehensions, and JIT-friendly constructs), reducing overhead in hot paths. Introduced Final constants and lru_cache for regex compilation to speed up repeated operations. [1] [2]
• Unified and streamlined parameter conversion methods (_convert_params_single_pass, _convert_named_params_with_casting, and _process_parameters) to minimize redundant iterations and centralize UUID-to-bytes logic. [1] [2] [3]
• Improved DML (INSERT/UPDATE/DELETE) detection and query handling by introducing a fast _check_dml helper, optimizing multi-row executemany and DML execution paths. [1] [2]

Benchmarking and testing:

• Enhanced the benchmark script (performance_comparison.py) to warm up both database connections before timing, and to run asyncpg first, giving psqlpy the "second run" advantage for a fairer comparison.

Other changes:

• Updated the package version to 0.1.1b4 in both psqlpy_sqlalchemy/__init__.py and pyproject.toml. [1] [2]

These changes collectively improve performance, maintainability, and the fairness of performance comparisons.…erns and caching for improved performance
