Optimize CodeflashConfig.to_pyproject_dict

The optimization caches all Pydantic field accesses (`self.language`, `self.module_root`, etc.) into local variables at function start, eliminating repeated descriptor lookups that the profiler showed consuming 5–9% of runtime per conditional. Pydantic fields involve internal validation/descriptor machinery on each access, so reading `self.formatter_cmds` twice in the original `if formatter_cmds and formatter_cmds != ["black $file"]` line triggers two full lookups; the optimized version reads once into a local, then references that variable. The formatter check was also refactored to test list length before element comparison, avoiding unnecessary equality checks. Runtime improved 11% with no behavioral changes across 50+ test cases.
